This CRF polychoron can be obtained from srico by partial Stott contracting only 8 cos. (Note that srico is just the convex hull of those 24 accordingly placed coes. Here 8 of those are selected in a hexadecachoral relative subsymmetry. The 16 other coes then get contracted in turn into tets. Also all 24 sircoes become squobcues. And 32 of the former 96 trips, in fact those which connected the now contracted coes, just become reduced to edges.)

Conversely it can be obtained by a similar partial Stott expansion from poxic (which in turn is derived by such a expansion from ico).

Finally it can be obtained as the augmentation of tat by 8 co || tic segmentochora, replacing thus all the tics and the new squacues thereby unite pairwise into squobcues.
