Zucca's Challenge Problem for Extrominoes
Livio Zucca's
Tetrominoes
Challenge Page challenges you to find plane regions
that can be tiled with each of a given set of tetrominoes and no others.
Here I show solutions to the corresponding
problem for extrominoes, or extended trominoes—figures
formed by joining three
equal squares orthogonally at edges or corners.
They are also called trikings and triplets.
If you find a smaller solution for any of these sets, please
let me know.
