A grid diagram of a trefoil.

Grid diagram of knots and links in lens spaces meld well with the "prism" triangulations. Here we illustrate this point with a grid diagram of the trefoil. Recall that the "prism" model of S^3 has just one tetrahedron. Since we're using a grid number 5 diagram, this tetrahedron is further subdivided into 25 tetrahedra. #grid_diagram #knot #math #tetrahedron #topology #trefoil
