An Apollonian gasket, also called an Apollonian net or Apollonian circle packing, is a fractal generated by starting with three mutually tangent circles and successively filling in further circles, each tangent to three others already in the figure. It is named after the Greek mathematician Apollonius of Perga.

Origin YearEarliest known written description per this source; the name honors the ancient Greek mathematician Apollonius of Perga, and the first modern mathematical definition was later given by Kasner and Supnick. Connections
Is Kind Of Object
Entity-backed identity for the object-kind enum value this mathematical object already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The object-kind fact itself stays on the object unchanged.
