Vertex Figure
The vertex figure of the grand antiprism is a dissected regular icosahedron: a regular icosahedron with two vertices removed. In their place 8 triangles are replaced by a pair of trapezoids, edge lengths φ, 1, 1, 1 (where φ is the golden ratio), joined together along their edge of length φ, to give a tetradecahedron whose faces are the 2 trapezoids and the 12 remaining equilateral triangles.

Famous quotes containing the word figure:
“We met. But all
We did that day was mingle great and small
Footprints in summer dust as if we drew
The figure of our being less than two
But more than one as yet.”
—Robert Frost (1874–1963)
