Can higher dimensional spheres be regularly partitioned/discretized?

A circle can be partitioned into $ninmathbb{N}$ congruent 1-spherical line segments similar to the regular polygons.



A sphere can be partitioned into $nin{4,6,20}$ congruent 2-spherical equilateral triangles similar to the tetra-, octa-, and icosahedron.



Is that the end of the story, or is it possible to partition a glome into congruent 3-spherical tetrahedrons for some $n$s?

          The question is equivalent to asking for regular polytopes whose facets are simplices. There are two infinite families: the simplices themselves (which are generalizations of tetrahedra), and the cross-polytopes (which are generalizations of octahedra). In four dimensions, there is also the 600-cell.

            The question is equivalent to asking for regular polytopes whose facets are simplices. There are two infinite families: the simplices themselves (which are generalizations of tetrahedra), and the cross-polytopes (which are generalizations of octahedra). In four dimensions, there is also the 600-cell.
