Question

perl · Answer

there is a formula, eulers theorem

austinl · Answer

Yep, I am looking and it doesn't fit any named figures either.
Closest one I can find is Great icosahedron.

perl · Answer

Eulers theorem

For any polyhedron that doesn't intersect itself, the

    Number of Faces
    plus the Number of Vertices (corner points)
    minus the Number of Edges

always equals 2

This can be written: F + V - E = 2
