## Mathematical Model – Two Compounds of Stellated Dodecahedra

Accession Number: 2016.mat.5

Two brown paper models representing compounds of stellated dodecahedra. These are labelled with the following markings:

2016.mat.5a – Small Stellated Dodecahedra “{5/2, 3} – sharing the 8 vertices of a cube {4,3}”

2016.mat.5b – Great Stellated Dodecahedra “{2/5, 5} sharing the 8 vertices of a cube {4,3}”

Primary Materials: Cardboard

“2016.mat.5a” is marked with the number “38” and the words ““{5/2, 3} – sharing the 8 vertices of a cube {4,3}”

“2016.mat.5b” is marked with the number “39” and the words “{2/5, 5} sharing the 8 vertices of a cube {4,3}”

2016.mat.5a Longest dimension = 21cm; 2016.mat.5b Longest dimension = 22cm.

Function: Sculpture, Pedagogical

Condition: Excellent

Manufacturer: unknown

These models existed at the Dept. of Mathematics during the tenure of Dr. H.S.M. Coxeter, who provided the comments below.

“These are two compounds of stellated dodecahedra, the small stellated dodecahedron 5:5, and the great stellated dodecahedron 5:3, in each case they are cleverly put together so as to make a compound.” H.S.M. Coxeter. Dec. 23, 1999
