The relation to spid runs as follows: spid in trippy subsymmetry can be given as o(ox)x3x(ox)o x(uo)x&#xt. That will be transformed into x(ou)x3(-x)(o(-x))o x(uo)x&#xt (faceting, same vertex set). Then a Stott expansion wrt. the second node produces this polychoron.

Alternatively it can be obtained as a diminishing of srip: srip in trippy subsymmetry can be given as x(uo)xo x(ou)xx3o(xo)xo&#xt. Then a diminishing wrt. the last vertex level produces this polychoron.
