Brick-symmetric great icosahedron faceting

The , or bisgif is an orbiform polyhedron. It consists of 8 triangles and 4 pentagrams. As its name suggests, it is a faceting of the great icosahedron, and thus also of the small stellated dodecahedron.

It appears as a cell of the great digonal swirlprism.

Vertex coordinates
Its vertex coordinates are the same as those of the small stellated dodecahedron.
