Acronym ..., s∞o2s4x4x
Name alternating bistratic tosquat honeycomb

This honeycomb as a total can not be made uniform: The mere alternated faceting (here starting at grothaph) e.g. would use edges of 3 different sizes: |sefa(s4x)| = x(8,3) = w = 1+sqrt(2) = 2.414214 and |s2s| = x(4,2) = q = sqrt(2) = 1.414214, besides the remaining unit edges (refering to elements of s∞o2s4x4x here).

Even so this snub can be made all unit edged. However then it neither would become uniform nor scaliform, because pairs of the former trapezia would become adjoining coplanar squares, that is the ditetragonal trapezobiprisms then would become octagonal biprisms, which have an internal dihedral angle of 180°. In fact, this rescaled structure then happens to be quite similar to tassiph in its 2-coloring of the underlying tosquat: on the red squares there are stacks of monostratic square prisms (cube), on the yellow ones there are stacks of bistratic octagonal biprisms, based on all the even layers, and on the blue ones there are also stacks of bistratic octagonal biprisms, based on all the odd layers.
