Truncated icosidodecahedronとは 意味・読み方・使い方

語源

From truncated + icosidodecahedron, referring to a partial construction method for the figure. (The resultant figure requires further distortion to make the faces regular.)

名詞

truncated icosidodecahedron ‎(複数形 truncated icosidodecahedra または truncated icosidodecahedrons)

1. An Archimedean solid with 62 regular faces (12 decagons, 20 hexagons かつ 30 squares) and 180 edges.

使用する際の注意点

The term truncated icosidodecahedron is considered improper by some authors because the implied construction results in a figure whose faces are not regular, and further distortion is required to make them so. The synonym great rhombicosidodecahedron is thus often preferred, even though confusion may arise with the (small) rhombicosidodecahedron and the nonconvex great rhombicosidodecahedron.
