\(K_5\): a symmetric three-dimensional associahedron
\(\dim K_5=3,\quad |V|=14,\quad |E|=21\)
Symmetric 3D polytope: drag to rotate, scroll to zoom, click a vertex
Drag to rotate; scroll to zoom; click a vertex.
Start with the symmetric three-dimensional \(K_5\). Drag it to rotate and click a vertex. The \(K_6\) view is an adjustable shadow of a four-dimensional polytope. The arrow diagram writes the parenthesized products and associators.
