Here I show all the polyfetts with from 1 to 3 cells.
Two-sided polyfetts are identified under reflection as well as rotation. One-sided polyfetts are distinguished under reflection. That is, if a polyfett and its mirror image are distinct, both are counted.
As with polyaboloes (polytans), congruent shapes are identified, without regard to how they may be constructed from single cells.
