Semistellated triacontaditeron

The semistellated triacontaditeron, also known as the digonal-tetrahedral duoantitegum, is a convex isoteric polyteron with 16 identical joined decachora as facets. It can be obtained as the dual of the demipenteract.

It can also be seen as the convex hull of a triacontaditeron and a demipenteract in common D5 symmetry. If the triacontaditeron has edge length 1, the demipenteract has edge length $$\frac32 = 1.5$$.

The ratio between the longest and shortest edges is 1:1.5.
