Acronym ..., tah || grit Name (degenerate) tah atop grit Circumradius ∞   i.e. flat in euclidean space Confer general polytopal classes: decomposition

It either can be thought of as a degenerate 5D segmentotope with zero height, or as a 4D euclidean decomposition of the larger base into smaller bits.

Incidence matrix according to Dynkin symbol
