There also is a non-gyrated axial stack too: squacu + op + ortho squacu = sirco, one of the Archimedean solids. In fact, both have the same vertex figure all over. But sirco features full cubical symmetry, i.e. its symmetry acts transiently, while esquigybcu features a 4-fold antiprismatic symmetry only, thereby dividing its vertex set into 2 classes. Thence it can be called pseudouniform at most.
And just as sirco allows for a quasi-version, querco, this gyrated stack too will have an according quasi-version: rasquacu + inv stop + gyro rasquacu = gyquerco.
