Acronym snit Name pyritohedron,pyritosnub tetrahedron,o2o2o symmetric ike variant,vertex figure of hyperbolic cube + n-prism honeycomb ` ` Circumradius sqrt[a2+c2] Especially cube-dim-doe (c:a = F)   alternated toe (a,c,d) = (q,Q,h) Confer uniform variants: ike (c:a = f)   co (c:a = 1)   general polytopal classes: isogonal Externallinks  This polyhedron is isogonal only. It requires for 2 edge sizes a and d. (c here is a pseudo edge only.)

The transition a → c will result in qqo oqq qoq&#zx (co). Then the a edges also become pseudo ones too, the incidences then would differ accordingly.

The case d:a = 1, c:a = f results in the fxo xof ofx&#zx (ike).

The case (a,c,d)(q,Q,h) (where Q = 2q, i.e. c:a = 2) results in the Qqo oQq qoQ&#zh (alternated toe) and would reflect the mere alternated faceting wrt. a vertex alternation with starting figure toe.

The case d:a = f, c:a = F results in the Fxo xoF oFx&#zf (cube-dim-doe).
