Face vector	64, 128, 80, 16
Confer	general duoprisms: 8,n-dip   n,n-dip   n,m-dip   2n,m-dip   2n,2m-dip   uniform relative: srit   spic   segmentochora: {4} || op   related CRFs: cyted srit   cyte gysrit   bicyte gysrit   bipgy srit   general polytopal classes: noble polytopes

Augmenting {4} || op onto alternating ops would lead to the srit (which would have an even larger symmetry)!
