Octapletals are eight element rep-tiles, and are associated with the Perron
number `4(1+i)`. As they have eight elements there
is probably a large number of such tiles. Large numbers of tiles can be derived
from the c4-symmetric cyclic octapletals. A limited number of directly
derivable from the c2-symmetric linear octapletal, but these include
c2-symmetric tiles, from which more tiles can be derived, and so on.

Octapletals include

- 1 linear rep-tile.
- 14 demi-linear octapletals.
- caterpillar rep-tile
- 2 cyclic octopletals and related figures (10 illustrated)
- ovoid tile
