A graph that encodes local operations in mathematics
The flip graphs of a quadrilateral (top-left), a pentagon (top-right), and a hexagon (bottom).Examples of flips in dimension 1 (top-right), 2 (top-left and central row), and 3 (bottom row).
In mathematics, a flip graph is a graph whose vertices are combinatorial or geometric objects, and whose edges link two of these objects when they can be obtained from one another by an elementary operation called a flip. Flip graphs are special cases of geometric graphs.
Among noticeable flip graphs, one finds the 1-skeleton of polytopes such as associahedra[1] or cyclohedra.[2]
