Deltahedra and deltahedral surfaces

This page aims to collect all types of deltahedron and polyhedral surfaces composed of congruent equilateral triangles. If you know of one that is not listed here, please let me know. @tsurutana
Numerical method is required to construct some deltahedra. Here's a link to my add-on for regularizing triangle mesh with Blender.
このページは様々な形のデルタ多面体と正三角形集合で表現される曲面(Deltahedral surface)を収集しています。下記のリストに載っていない形を見つけたら@tsurutana までご連絡ください。
