Hyperbolic Forms
There are 9 Coxeter group families of compact uniform honeycombs in hyperbolic 3-space, generated as Wythoff constructions, and represented by ring permutations of the Coxeter-Dynkin diagrams for each family.
From these 9 families, there are a total of 76 unique honeycombs generated:
- : - 9 forms
- : - 15 forms
- : - 9 forms
- : - 11 forms (7 overlap with family, 4 are unique)
- : - 9 forms
- : - 6 forms

The full list of hyperbolic uniform honeycombs has not been proven and an unknown number of non-Wythoffian forms exist. One known example is in the {3,5,3} family.
There are also 23 noncompact Coxeter groups of rank 4. These families can produce uniform honeycombs with unbounded facets or vertex figure, including ideal vertices at infinity:

Famous quotes containing the word forms:
“We find the most terrible form of atheism, not in the militant and passionate struggle against the idea of God himself, but in the practical atheism of everyday living, in indifference and torpor. We often encounter these forms of atheism among those who are formally Christians.”
—Nicolai A. Berdyaev (1874–1948)
