except Jonathan Numbers, which are classes of sets of "Iterated Figurate 
Numbers" as defined in several of Jonathan Vos Post's publications as

1:
 many sequences of Figurate Numbers start with 1.  Hence, among 
     other things, 1 is the first of the Triangular, Square, Pentagonal,
     Hexagonal, Heptagonal, Octagonal, Nonagonal, Decagonal and other 
     Polygonal Numbers.  It is also, after 0, the first Square, Cube,
     4-D Hypercube, 5-D Hypercube, and so forth.  It is also the first of many
     Polyhedral Numbers such as the Tetrahedron Tet(0).
     It is also the first of an infinite number of multidimensional 
     Polytope Numbers such as the Pentatope (4-Simplex or Hypertetrahedron), 
     Hyperoctahedron, 24-cell, Hyperdodecahedron, and Hypericosahedron --
     these Polytope numbers are the subject of recent papers by this 
     author, see References.
