Comments

A "creature" in Palago is a closed shape of a single color across several Palago tiles, perhaps with one or more holes.

A Palago tile is a hexagonal tile with four regions of alternating colors. See links for illustrations.

Creatures are counted up to rotation, reflection, and swapping colors.
