Binary Pentagonal Flexagon

**Figure 13:** The binary pentagonal flexagon has two cycles, each of which has two vertices in common with the other one, for a total of eight.

**Figure 15:** Top side of the binary pentagonal flexagon cutout. The flexagon has ten faces, so this cutout provides material for just one of the sectors needed for the flexagon.
