Tiling the Owen Dodecagon With Three Didoms
A didom is a polyform
made by joining two doms,
2×1 right triangles,
at their short legs, long legs, half long legs, or hypotenuses.
All but one of the didoms conform to the polyomino (square) grid.
Here are the 13 didoms:
In 2000, Brendan Owen tiled an almost regular dodecagon
with two sets of the 13 didoms:
For an analysis of this tiling problem,

Below I show how to tile this dodecagon
with copies of three different didoms.
Only 8 sets of three didoms can be used to do this:
