In geometry, the icosahedral 120-cell, polyicosahedron, faceted 600-cell or icosaplex is a regular star 4-polytope with Schläfli symbol {3,5,5/2}. It...

In geometry, the great icosahedral 120-cell, great polyicosahedron or great faceted 600-cell is a regular star 4-polytope with Schläfli symbol {3,5/2...

600-cell, a regular 4-dimensional polytope. The 600-cell has icosahedral cross sections of two sizes, and each of its 120 vertices is an icosahedral pyramid;...

order-5 icosahedral 120-cell honeycomb is one of four regular star-honeycombs. With Schläfli symbol {3,5,5/2,5}, it has five icosahedral 120-cells around...

4-polytope Icosahedral 120-cell Small stellated 120-cell Great 120-cell Grand 120-cell Great stellated 120-cell Grand stellated 120-cell Great grand 120-cell Great...

stellation of the dodecahedron. Indeed, the small stellated 120-cell is dual to the icosahedral 120-cell, which could be taken as a 4D analogue of the great dodecahedron...

each 120-cell vertex. For example, in the #3 chord row, 24 #3 chords converge at each of the 120-cell's 600 vertices, forming a double icosahedral vertex...

tetrahedral 600-cell), pI=polyicosahedron {3,5,⁠5/2⁠} (an icosahedral 120-cell), and pD=polydodecahedron {5,3,3} (a dodecahedral 120-cell), with prefix...

the same edge arrangement as the 600-cell, icosahedral 120-cell and the same face arrangement as the great 120-cell. It could be seen as another 4D analogue...

icosahedral cell in place of each removed icosahedral pyramid. The snub 24-cell thus has 24 icosahedral cells and the remaining 120 tetrahedral cells...
