The rule changes a bit...
Division by 3:
Remainder of 1 -> ØA
Remainder of 2 -> ØB
Remainder of 0 -> ØC
Actually, I take that back. The error is plainly obvious if one labels left odds and right evens. Space #2 would be ØA, not ØB.:thumbsup::thumbsup:
Now if you numbered consecutively left first, top to bottom, then right, it would work.
