Tridecahedron

A tridecahedron is a polyhedron with thirteen faces. There are numerous topologically distinct forms of a tridecahedron, for example the dodecagonal pyramid and hendecagonal prism.

Convex

There are 96,262,938 topologically distinct convex tridecahedra, excluding mirror images, having at least 9 vertices.[1] (Two polyhedra are "topologically distinct" if they have intrinsically different arrangements of faces and vertices, such that it is impossible to distort one into the other simply by changing the lengths of edges or the angles between edges or faces.) There is a pseudo-space-filling tridecahedron that can fill all of 3-space together with its mirror-image.[2]

Examples

The following list gives examples of tridecahedra.

gollark: Why are you using knots and not duct tape? In general.
gollark: Me.
gollark: You can delay it if you have an excuse, like implementing the SHA256 button.
gollark: I do.
gollark: <@319753218592866315> You should have an "export guesses and generate SHA256" button.
