OctaPentas – The Pieces

OctaPentas – a Puzzle Based on Regular Octagons and Pentagons

The OctaPenta grid is composed of regular octagons and pentagons, in a ratio of 1:4 — each octagon is surrounded by four pentagons.

From these two base shapes, a total of 13 distinct polyforms can be constructed:
6 OctaPentas consist of one octagon connected to two pentagons, and 7 additional ones combine one octagon with three pentagons.

For the puzzle, 9 of these 13 OctaPentas were selected.
