Little effort has been made to tile objects with the **polyiamonds** larger than the heptiamonds. Perhaps this is because the number of different **polyiamonds** quickly gets into the thousands. Bit map vector programming can easily take a subset of the larger **polyiamonds** ( < 50 different tiles) and tile a space. Finding **polyiamond** sets with under 50 members allows for a complete description of the tiling possibilities. George Sichermann has a set of 25 order 10 unitary polyiamonds. There is a set of 46 sphinx tile dominoes. Otherwise random sets are used. Adding on tiles to the core smaller orders is useful. I have used Walter Trump’s tiling program to produce the following examples. More author’s work in this direction can be seen at the following links:
