# Tessellation Featuring Squares, Rhombi, and Isosceles Triangles

I made this by modifying the well-known tessellation of squares and regular octagons.

# Compound of Four Pyramids

I made this using *Stella 4d*, which you can try for free right here.

# Two Symmetrohedra

Symmetrohedra are symmetric polyhedra with many faces regular, but not necessarily all of them. The symmetrohedron shown above is the dual of the convex hull of the compound of the great rhombicosidodecahedron and its dual, the disdyakis triacontahedron. All of its faces are regular, except for the triangles, which are scalene.

The second symmetrohedron shown here is the dual of the convex hull of the great rhombcuboctahedron and its dual, the disdyakis dodecahedron. Like its “big brother” above, all of this symmetrohedron’s faces are regular, except for the scalene triangles.

These polyhedra were made using *Stella 4d*, a program you can try for free at this website.
