caption_attribution_description: This picture shows a 2-3 Pachner move: a union of 2 tetrahedra gets decomposed into 3 tetrahedra.
context_page_description: In topology, a branch of mathematics, Pachner moves, named after Udo Pachner, are ways of replacing a triangulation of a piecewise linear manifold by a different triangulation of a homeomorphic manifold. Pachner moves are also called bistellar flips. Any two triangulations of a piecewise linear manifold are related by a finite sequence of Pachner moves.
