Abstract
We develop the notion of a Kleinian Sphere Packing, a generalization of
“crystallographic” (Apollonian-like) sphere packings defined in [A. Kontorovich and K. Nakamura,
Geometry and arithmetic of crystallographic sphere packings,
Proc. Natl. Acad. Sci. USA 116 2019, 2, 436–441].
Unlike crystallographic packings, Kleinian packings exist in all dimensions, as do “superintegral” such.
We extend the Arithmeticity Theorem to Kleinian packings, that is, the superintegral ones come from
