Noun
24-cell (plural 24-cells)
(geometry) A four-dimensional polytope whose twenty-four bounding facets are octahedra and which has no three-dimensional analogue.
As cells must fit around an edge, : * The rectified 16-cell is the regular 24-cell and vertices are all equivalent octahedra are regular bipyramids. Source: Internet
This decomposition of the cuboctahedron corresponds with the cell-first parallel projection of the 24-cell into three dimensions. Source: Internet
These elements correspond with the images of six of the octahedral cells in the 24-cell, the nearest and farthest cells from the 4D viewpoint, and the remaining eight pairs of cells, respectively. Source: Internet
