Acronym ..., {4} || perp {4}
Name (degenerate) square atop fully orthogonal square
Circumradius ∞   i.e. flat in euclidean space
Dual selfdual
Confer
general polytopal classes:
lace simplices   decomposition  

It either can be thought of as a degenerate 5D segmentotope with zero height, or as a 4D euclidean decomposition. In fact it amounts into a fold of hex, which is its hull, plus the 2 completely orthogonal decompositions thereof into 4 squascs each.
