The unit is a variant of an edge unit; I call usage like this the “face variant” since the unit covers a face rather than an edge of the solid. When I invented the module, I thought it was very original, but soon I learned it was actually pretty common and had been independently designed by many others before (it’s just a variant of the classic Ow’s edge unit). Dave Mitchell invented this “face configuration” (under the name Cube-Corner Star) as early as 1993.
