Acronym n-aw, {2n} || n-ap Name anti-n-wedge,n-gonal anti-wedge,2n-gon - n-antiprismatic wedge,n-gonal gyrobicupolaic ring,{2n} || n-antiprism,{n} || gyrated n-cupola Segmentochoron display Circumradius sqrt[(3-2 cos(π/n))/(5-6 cos(π/n))] Lace cityin approx. ASCII-art ``` x-n-x x-n-o o-n-x ``` Confer general polytopal classes: segmentochora Especially {4} || tet (n=2)*   {6} || oct (n=3)   {8} || squap (n=4)   {10} || pap (n=5)

* The case n=2 equally would be considerable here by concept, it just has a different incidence matrix as the n-gons become degenerate.

Incidence matrix according to Dynkin symbol
