The relation to ex runs as follows: ex in pentic subsymmetry can be given as ((xffoo3oxoof3fooxo3ooffx))&#zx. That will be transformed into (((-x)ffoo3xxoof3fooxo3ooffx))&#zx. Then into ((offoo3(-x)xoof3Fooxo3ooffx))&#zx. Finally once more into ((oFfoo3(-x)(-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

((oFfoo3ooxxF3Fxoxo3ooffx))&#zx   → all heights = 0 – except those of the not existing lacing(1,2), lacing(1,3), lacing(1,5), lacing(2,4), and lacing(2,5)
