I'd stick with t{2,n}, truncated hosohedra as
Coxeter expresses, and just leave the dihedrons in peace. Or say a dihedron is a degenerate prism with height of zero (it already says that).

Hmmm... Cantellation isn't usually applied across 2 branches. t{2,n} works better, or a bitruncation from a dihedron as 2t{2,n}.
