Acronym phexdo Name partially hexa-expanded dodecahedron ` ©` (phexdo is the extremal form of this animation) Vertex figure [52,r2], [3,r,5,R], [5,R2] Confer uniform variant: doe   general polytopal classes: partial Stott expansions

The vertex angles of the rhombs {(r,R)2} are r = arccos[(sqrt(5)-1+2 sqrt[5-sqrt(5)])/sqrt(32)] = 36.264662° resp. R = arccos[-(sqrt(5)-1+2 sqrt[5-sqrt(5)])/sqrt(32)] = 143.735338°.
