Acronym tidtes Name tetra-diminished tesseract ` ©` Circumradius 1 Coordinates (1/sqrt(2), 1/sqrt(2), 0, 0)   & all changes of sign (0, 1/sqrt(2), 1/sqrt(2), 0)   & all changes of sign (0, 0, 1/sqrt(2), 1/sqrt(2))   & all changes of sign Pattern ```A---B---A---B--- | / | \ | / | \ C---+---C---+--- | \ | / | \ | / A---B---A---B--- | / | \ | / | \ C---+---C---+--- | \ | / | \ | / (vertical B-B lines of each column resp. horizontal C-C lines of each row are to be identified) ``` Confer uniform relative: tes

It is known that ico can be given within 2 different, dual positionings and that tes can be vertex inscribed into it. This gives rise to a 4-coloring of the tes vertices similar to the above mentioned coordinates, in fact in here simply one color is being omitted, yielding their new cells underneath, q-tets. Each cube as a cell remains in here, but it will become a diamond wedge: 2 diametral vertices of one of the square prism bases will be cut off.
