In tendimensional geometry, a 10polytope is a 10dimensional polytope whose boundary consists of 9polytope facets, exactly two such facets meeting at each 8polytope ridge.
A uniform 10polytope is one which is vertextransitive, and constructed from uniform facets.
Regular 10polytopes can be represented by the Schläfli symbol {p,q,r,s,t,u,v,w,x}, with x {p,q,r,s,t,u,v,w} 9polytope facets around each peak.
There are exactly three such convex regular 10polytopes:
There are no nonconvex regular 10polytopes.
The topology of any given 10polytope is defined by its Betti numbers and torsion coefficients.^{[1]}
The value of the Euler characteristic used to characterise polyhedra does not generalize usefully to higher dimensions, and is zero for all 10polytopes, whatever their underlying topology. This inadequacy of the Euler characteristic to reliably distinguish between different topologies in higher dimensions led to the discovery of the more sophisticated Betti numbers.^{[1]}
Similarly, the notion of orientability of a polyhedron is insufficient to characterise the surface twistings of toroidal polytopes, and this led to the use of torsion coefficients.^{[1]}
Uniform 10polytopes with reflective symmetry can be generated by these three Coxeter groups, represented by permutations of rings of the CoxeterDynkin diagrams:
#  Coxeter group  CoxeterDynkin diagram  

1  A_{10}  [3^{9}]  
2  B_{10}  [4,3^{8}]  
3  D_{10}  [3^{7,1,1}] 
Selected regular and uniform 10polytopes from each family include:
The A_{10} family has symmetry of order 39,916,800 (11 factorial).
There are 512+161=527 forms based on all permutations of the CoxeterDynkin diagrams with one or more rings. 31 are shown below: all one and two ringed forms, and the final omnitruncated form. Bowersstyle acronym names are given in parentheses for crossreferencing.

There are no compact hyperbolic Coxeter groups of rank 10, groups that can generate honeycombs with all finite facets, and a finite vertex figure. However, there are 3 paracompact hyperbolic Coxeter groups of rank 9, each generating uniform honeycombs in 9space as permutations of rings of the Coxeter diagrams.
