ASCII-art ```o o f f o o x x v ``` ``` f v v f x x o o ``` Dihedral angles (at margins) at singular long edge:   arccos(1/sqrt(5)) = 63.434949° at all other edges:   arccos(-1/sqrt(5)) = 116.565051° Confer uniform relative: doe   gad

This polyhedron can also be obtained as a stellation of doe by blending at 2 neighbouring pentagons with tall pyramids, which are the tips of sissid and then inserting inbetween a wedge type simplex, as is used for gad.

The faces are regular pentagons of side v = (sqrt(5)-1)/2 = 0.618034; kites {(k,K,K,K)} with corner angle k = 36° and K = 108°, where side KK has size v again, diagonal KK has size x = 1, side kK has size f = (1+sqrt(5))/2 = 1.618034, and the diagonal kK has size sqrt[(5+sqrt(5))/2] = 1.902113; and trapzia {(t,t,T,T)} with corner angle t = 72° and T = 108°, where the side TT has size v again, while the other sides tT and tt have both size f again.
