The relation to ex runs as follows: ex in pentic subsymmetry can be given as xffoo3oxoof3fooxo3ooffx&#zx. That will be transformed into xFfoo3o(-x)oof3fxoxo3ooffx&#zx. Then a Stott expansion wrt. the second node produces this polychoron.

The non-existing lacings calculate to vertex distances according to f=(1+sqrt(5))/2.

Incidence matrix according to Dynkin symbol

xFfoo3xoxxF3fxoxo3ooffx&#zx   → all heights = 0 – except those of the not existing lacing(2,4) resp. lacing(2,5).
