Square cubic truncatriate (EntityTopic, 11)

From Hi.gher. Space

The square cubic truncatriate is a powertope formed by taking the cubic truncate of the square. It is therefore the convex hull of three irregular hexeracts, each being the trioprism of squares of side 1, 1+√2 and 1+√2, oriented with the small squares of each trioprism in unique axes.
