general polytopal classes:
isogonal  

These isogonal polychora are obtained by M-prism alternation of the uniform 4N,M-duoprism (with N > 1, M > 2).

As mere alternations these come out to be nothing but 2N,M-duoprism variants. In fact, they then are yNx xMo with y=x(4N,3). Accordingly those obviously well could be resized to all unit edge lengths generally.
