A pyramid polyomino is a polyomino in the form of a triangle
with two zigzag edges.
A pyramid prism polycube
is a polycube prism whose base is a pyramid polyomino.
Here I show the smallest known pyramid prism polycubes that can be tiled with copies of of a tetracube.
If you find a smaller solution, or solve an unsolved case, please write.
