icosidodecahedronn.

Etymology: < Greek εἴκοσι twenty + δώδεκα twelve + ἕδρα seat, base.Previous versions of the OED give the stress as: ˌicosiˌdodecaˈhedron.

Geometry.

A solid contained by twenty equilateral triangles and twelve regular pentagons, formed by replacing the twelve solid angles of the regular icosahedron by planes corresponding to the faces of a regular dodecahedron.
