List of E6 polytopes : ウィキペディア英語版 | List of E6 polytopes
In 6-dimensional geometry, there are 39 uniform polytopes with E6 symmetry. The two simplest forms are the 221 and 122 polytopes, composed of 27 and 72 vertices respectively. They can be visualized as symmetric orthographic projections in Coxeter planes of the E6 Coxeter group, and other subgroups. == Graphs ==
Symmetric orthographic projections of these 39 polytopes can be made in the E6, D5, D4, D2, A5, A4, A3 Coxeter planes. Ak has ''k+1'' symmetry, Dk has ''2(k-1)'' symmetry, and E6 has ''12'' symmetry. Six symmetry planes graphs are shown for 9 of the 39 polytopes in the E6 symmetry. The vertices and edges drawn with vertices colored by the number of overlapping vertices in each projective position.
