For this polychoron the augmentations of the dips of tiddip by pepufs is to be done in this orientation ("gyro") that the squippies of pepuf pairwise adjoin to each other back to back. – There is a different orientation of the pepufs as well ("ortho"), using then the trips to adjoin pairwise back to back. This then would result in twau tiddip.
