Black = purple white = lavendarMy rough prototype model made yesterday

Original problem illustrations

Top two are correct

These are wrongyet seemed rightYesterday…

Ooops!

This was the patternmy model producedyesterday

Original problem illustrations

It produces this view It produces this view But does notproduce this view

If the left drawing is correctthen the pattern that wouldform is one of these two patterns

If the middle drawing is correctthen the pattern, that wouldform it, is one of these two

If the right drawing is correctthen the pattern, that wouldform it, is one of these two

Now let’s place the 3 patterns together to formthe complete pattern for the cube (all 6 panels)

Now let’s place the 3 patterns together to formthe complete pattern for the cube (all 6 panels)

Rearranging these 3 patternsforms this pattern and formsa cube which the 3 views match.

Thus proving sensei Say Keng Lee correctand lowly pilgrim Alan wrong.
