Similar to bidex, the diminishing of ex at the vertices of 2 inscribed f-icoes, this isogonal polychoron is obtained as a diminishing of tex at the vertices of 2 inscribed sqrt[6+sqrt(5)]-exes. In contrast to the former will the latter neither be noble, in fact it uses 3 types of cells (one of which is a mono-shaved tut as displayed to the right – also related to the parabi-shaved one, i.e. the rectagonal trapezoprism), nor scaliform, in fact it uses 2 edge sizes.

A general vairiant might be used so, having 3 edge sizes a, b, and c = a+b. Still, that size class b further divides into 3 classes by incidence, cf. below. The specific variant here, relating to a diminishing of the uniform tex variant, only uses 2 edge sizes so, in fact a = b = x and hence c = u.

A different variant would be obtained when using a = 0, thus having accordingly different incidences so. That one then becomes a solely b-edged spidrox. And the above mentioned shaved tut simply becomes a b-squippy thereby.
