The [[snub demitesseract]], incorrectly referred to as the ''snub 24-cell'', can be formed by the construction of ''alternated truncated 24-cell'' or ''alternated cantitruncated 16-cell'' - but in order to be a snub of one of these families, the alternation would need to be of the parent's omnitruncate, and it is not.

When correctly represented, the snub demitesseract's Coxeter-Dynkin symbol is that of a three-pronged star, with all four nodes as snub rings.

=== The grand antiprism ===
There is one (convex, Euclidean, non-prismatic) uniform polychoron not part of any of the above families, known as the [[grand antiprism]]. Because it doesn't exist within any family above, it is non-Wythoffian and has no Dx number, CD or Schlaefli symbols. It is loosely analogous to the three-dimensional antiprisms, which consist of two parallel polygons joined by a band of triangles. Unlike them, however, the grand antiprism is not a member of an infinite family of uniform polytopes.

Singularities

The snub demitesseract

The snub demitesseract, incorrectly referred to as the snub 24-cell, can be formed by the construction of alternated truncated 24-cell or alternated cantitruncated 16-cell - but in order to be a snub of one of these families, the alternation would need to be of the parent's omnitruncate, and it is not.

When correctly represented, the snub demitesseract's Coxeter-Dynkin symbol is that of a three-pronged star, with all four nodes as snub rings.

The snub demitesseract has 144 cells, 480 faces, 432 edges and 96 vertices.

  • Its cells are 24 icosahedra and 120 tetrahedra. They are joined with three icosahedra and five tetrahedra around each vertex.
  • Its faces are all triangles.

The grand antiprism

There is one (convex, Euclidean, non-prismatic) uniform polychoron not part of any of the above families, known as the grand antiprism. Because it doesn't exist within any family above, it is non-Wythoffian and has no Dx number, CD or Schlaefli symbols. It is loosely analogous to the three-dimensional antiprisms, which consist of two parallel polygons joined by a band of triangles. Unlike them, however, the grand antiprism is not a member of an infinite family of uniform polytopes.

Its elements are 320 cells, 720 faces, 500 edges and 100 vertices.
