Dodecahedron6-Compound
Paper sculpture of the dodecahedron 6-compound by E. Herrstrom

An attractive compound can be obtained by combining six dodecahedra, each rotated by 1/10 of a turn about the line joining the centroids of opposite faces. The illustration at right above shows a paper sculpture of the dodecahedron 6-compound.

It is implemented in Mathematica as PolyhedronData["DodecahedronSixCompound"].

Dodecahedron6-CompoundNet

A net for constructing the compound is illustrated above, where

s_1=sqrt((17)/(40)-7/(8sqrt(5)))
(1)
s_2=1/(76)sqrt(1826-726sqrt(5))
(2)
s_3=1/4(3-sqrt(5))
(3)
s_4=1/(290)sqrt(5830+50sqrt(5))
(4)
s_5=1/(10)(5-sqrt(5))
(5)
s_6=1/(38)(9+sqrt(5))
(6)
s_7=1/2(3-sqrt(5))
(7)
s_8=1/5sqrt(5)
(8)
s_9=1/(38)sqrt(4646-1882sqrt(5))
(9)
s_(10)=1/2(sqrt(5)-1).
(10)

The surface area of the compound is

 S=9/(2204)sqrt(22328650+7771490sqrt(5)).
