Polyhedra in Polyhedra: packings with certificates
An interactive catalogue of known small-container packings for 2–40 copies of several polyhedron families, with 3D viewing and coordinate checks.
- For
- Researchers and geometry enthusiasts comparing packings, inspecting constructions, or checking candidate arrangements
- Worth noticing
- Coordinate records use number-field coordinates, rational rotations, and a separating plane for every pair of pieces.
Field notes
Visitors choose a solid family, container problem, and copy count, then inspect constructions in a rotatable 3D viewer; the page also charts volume bounds and published comparisons. Coordinate-backed records carry exact certificates using number-field coordinates, rational rotations, and pairwise separating planes, while source-only values are labeled separately when downloadable coordinates are unavailable. The project invites browser-side checks and says submitted candidates are certified by a GitHub Action; it explicitly does not claim optimality.
