This page shows possible placements of the solids with
diamonds or squares on two outside edges (stripes) of the overall configuration,
and the opposite (squares or diamonds, respectively) between them.
There are 34 possible placements of the solids for the left/right diamond placements.
There are 25 possible placements of the solids for the top/bottom diamond placements.
Three of them show up on both lists:
0,14,22
1,14,22
2,10,14
There are just 8 possible choices for left/right square placements.
Note that in each case, there are single-color stripes where
the diamonds and squares meet.
Left/right: vertical stripes at 11,17,...,99,105 and 14,20,...,102,108.
Top/bottom: horizontal stripes at 22,23...,30,31 and 88,89,...,96,97.
