Patterns in Prime Numbers:Fixed Digits Repetitions

Inder J. Taneja1

Abstract

In this paper, we shall work with prime numbers in such a way that they can be extended byinserting digits in repeated ways, and still it continues prime numbers. These types of prime numberscalled ”Patterns in Prime Numbers”. The repetition of digits are with one, two, three, four, five and sixdigits. This work is from 10 to 7 string length 7, i.e., in each case we have 10 to 7 primes numbers withrepeated digits.

The work of this paper is divided in sections and subsections given below:

1 Introduction;1.1 Multiple Prime Patterns;2 Patterns with Strings of Length 10;2.1 Single Digit Repetitions;2.2 Double Digits Repetitions;2.3 Triple Digits Repetitions;2.4 Four Digits Repetitions;3 Patterns with Strings of Length 9;3.1 Single Digit Repetitions;3.2 Two Digits Repetitions;3.3 Three Digits Repetitions;3.4 Four Digits Repetitions;4 Patterns with Strings of Length 8;4.1 Single Digit Repetitions;4.2 Two Digits Repetitions;4.3 Three Digits Repetitions;4.4 Four Digits Repetitions;4.5 Five Digits Repetitions;5 Patterns with Strings of Length 7;5.1 Single Digit Repetitions;5.2 Double Digits Repetitions;5.3 Triple Digits Repetitions;5.4 Four Digits Repetitions;5.5 Five Digits Repetitions;5.6 Six Digits Repetitions.

1 IntroductionFirst let us understand what we mean by ”patterns in prime numbers”. It is understood as repetitionof same digits in limited continuous way the the resulting number still remains as prime numbers. Seesome examples,

• 71701700170001700001.

• 11116141116141614111614161416141116141614161416141.

• 106910186910181869101818186910181818186910181818181869.

• 474135741351357413513513574135135135135741351351351351357.

Let us analyse the above prime numbers. In the first case digit 0 repeats 4 times. In the second casethe the digit 1614 repeats 4 times. In the third and forth examples, the numbers 18 and 135 repeats 5times respectively. Also to note that in each case the next number in the string are not prime numbers.See below:

700001 = 197× 35533;1161416141614161416141 = 82549× 14069415033666809;

1018181818181869 = 11× 92561983471079;41351351351351351357 = 29× 9461× 597643× 252181271.

Let us examine two interesting examples (refer [2]),

• 31331333133331333331333333133333331.

• 5959959999599999599999995999999999959999999999999.

The difference between two examples is that the first is uniform in increasing single digit 3 to next.In the first case the string can start at any place. The next example in this case is not a prime,

333333331 = 17× 19607843.

The second example is not uniform. In this case the next of similar time prime number is

59999999999999999999999.

Our study is limited to the examples of first kind, i.e., uniform patterns. This is divided in sectionsand subsections according to number of primes in each category. This work is limited to 7 to 10 stringsof primes, but is written below in reverse order i.e., from 10 to 7. Thus in each case, single, double,triple, ... digits repetitions are done separately. In each case few examples are given. By no means,these only examples, there might be much more.

1.1 Multiple Prime PatternsBelow is a example of a prime number 50487611, where the pattern of lenght 9 is formed by threedifferent ways, by digits 489, 894 and 948 respectively.

I 50 48761150 489 48761150 489 489 48761150 489 489 489 48761150 489 489 489 489 48761150 489 489 489 489 489 48761150 489 489 489 489 489 489 48761150 489 489 489 489 489 489 489 48761150 489 489 489 489 489 489 489 489 487611.

I 504 87611504 894 87611504 894 894 87611504 894 894 894 87611504 894 894 894 894 87611504 894 894 894 894 894 87611504 894 894 894 894 894 894 87611504 894 894 894 894 894 894 894 87611504 894 894 894 894 894 894 894 894 87611.

I 5048 76115048 948 76115048 948 948 76115048 948 948 948 76115048 948 948 948 948 76115048 948 948 948 948 948 76115048 948 948 948 948 948 948 76115048 948 948 948 948 948 948 948 76115048 948 948 948 948 948 948 948 948 7611.

We observe that in all the 3 cases the primes are the same in each line, for example, the last one ineach case is 50489489489489489489489489487611. Only difference is in way the digits for repetitionare choosed. This is due the fact that 48 is appearing in the prime as well as in the repetition digit:5048(948)7611. For simplicity, let us call the as ”multiple pattern prime numbers”. The detailed studyon this type of prime numbers shall be dealt elsewhere.

For study on numbers in different situations can be seen in author’s work [6]. This work is summary ofauthor’s on numbers work for the past few years. See also author’s recent work [7] on Hardy-Ramanujannumber 1729. This work brings the number 1729 in different situations. From historical point of view,refer [1, 2, 4, 5].

2 Patterns with Strings of Length 10In this section, we shall give examples of patterns with different digits repetitions for primes length 10.This has be divided according digits in the subsections below.

2.1 Single Digit RepetitionsIn this case, we have only one example,

I 291234 73291234 3 73291234 3 3 73291234 3 3 3 73291234 3 3 3 3 73291234 3 3 3 3 3 73291234 3 3 3 3 3 3 73291234 3 3 3 3 3 3 3 73291234 3 3 3 3 3 3 3 3 73291234 3 3 3 3 3 3 3 3 3 73.

There might be more examples, but we found only one.

2.2 Two Digits RepetitionsIn this case also we have only one example,

I 125931 97125931 33 97125931 33 33 97125931 33 33 33 97125931 33 33 33 33 97125931 33 33 33 33 33 97125931 33 33 33 33 33 33 97125931 33 33 33 33 33 33 33 97125931 33 33 33 33 33 33 33 33 97125931 33 33 33 33 33 33 33 33 33 97.

Again, there might be more examples of this kind.

2.3 Three Digits RepetitionsBelow are few examples of 3 digits repetitions.

There may be much more of this kind, but we found only one.

3 Patterns with Strings of Length 9In this section, we shall give examples of patterns with different digits repetitions for primes length 9.This has be divided according digits in the subsections below.

3.1 Single Digit RepetitionsBelow are few examples, with simplified notations.

Above two patterns we have written in two different ways. Left side is simplified notation, whileright side is complete patterns. Instead writing whole the pattern, we can write is int reduced formrepresenting the same way. The left side is understood as

[A, B; k ]where A is prime numbers, B is prime number with repetition of digits. The letter k represents the totalprime numbers. In the above two cases, k=9 . Thus, above two examples can equivalently be written as,

• [6073, 69073; 9]• [47881, 437881; 9].

From now onwards, we shall use frequently, these noations. Below are more examples,

4 Patterns with Strings of Length 8In this section, we shall give examples of patterns with different digits repetitions for primes length 8.This has be divided according digits in the subsections below.

4.1 Single Digit RepetitionsBelow are few examples, with simplified notation.
