Pentiles-1
The Grid
The Set: 4 pentiles
The Set: 1-3 pentiles
The Idea
The 17 pentiles are one over the number to fill a diamondshape (actually the circumfence is a square). Thus one piece must be left out, and only these three comply. The remaining 16 fill the shape in many ways, and these are three of them.
Here are two 5-hex solutions using the 1-3 pentiles set .
There are two, and only two, 4-hex solutions using the 3 pentiles set and an additional single pentile.
Obviously we wouldn't deny you a '22 hexes' solution with the full 1-4 set.
