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 14:
Permutation of the pentagons along the strip for a binary pentagonal flexagon.

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.
