It represents 3x6. 666.

This is your brain on Common Core.

Edit: I have one better:

63 is 10, 10 is 3, 3 is 5, 5 is 4 and 4 is cosmic.

36 is 8, 8 is 5, 5 is 4, and 4 is cosmic.

666 is 18, 18 is 8, 8 is 5, 5 is 4, and 4 is cosmic.

Sixty three thousand is 18, 18 is 8, 8 is 5, 5 is 4, and 4 is cosmic.

There is a pattern there, you just found the wrong one.

It represents 3x6. 666.
