Tetragonal expanded antitrapezohedron (EntityTopic, 3)

From Hi.gher. Space

The tetragonal expanded antitrapezohedron is alternable. As shown above it is not a zonotope, but can be deformed into a zonotope with surplus facets (180 degree angles) with 5 generators, two pairs of them colinear.

I will write a better page for it later.

The trig/pentagonal expanded antitrapezohedra look similar, just with 3 or 5 vertical "slices" instead of the 4 here.
