Inflated Didoms
A didom is a polyform
made by joining two doms,
diagonal half-dominoes,
at their short legs, long legs, hypotenuses, or half long legs.
Here are the 13 didoms:
In 1994 Rodolfo Kurchan introduced inflated pentominoes.
These were rectangular arrangements of the 12 pentominoes, in which some
pentominoes were scaled up by an integer factor.
Here I show convex arrangements of the 13 didoms,
in which some didoms are scaled up by an integer factor or √5
times an integer factor.
