bistratic lace towers  

This CRF occurs as genuine multistratic segment of spic, in fact its bistratic oct-first central segment.

It also occurs as orbiform member of the set of prisms o3xNx x, gyro-augmented by magnabicupolaic rings, i.e. {N} || 2N-prism segmentochora, which occurs in the case N=4. For this polychoron the augmentations of the ops of ticcup by squipufs is to be done in this orientation ("gyro") that the squippies of squipuf pairwise adjoin to each other back to back. Additionally, as these happen to be corealmic here, they even combine into octs. – There is a different orientation of the squipufs as well ("ortho"), using then the trips to adjoin pairwise back to back. This then would result in hau ticcup.
