He is one of four collegiate coaches to win at least 400 duals matches. Laves lattices are the duals to the Archimedean lattices. It is scheduled to continue at the 2015 Collegiate Cup Duals in Dalton again. The duals of isotoxal polygons are isogonal polygons. The 3-connected polyhedra are the duals of the deltahedra. Because the uniform tilings are isogonal, the duals are isohedral. Uniform tilings and their duals are all edge-to-edge. The Archimedean solids and their duals can also be stellated. By definition, this isotopic property is common to the duals of the uniform polytopes. These are the duals of the two quasi-regular Archimedean solids. In 3-dimensional honeycombs, the catoptric honeycombs, duals to the uniform honeycombs are isochoric. They are the geometric duals of Voronoi diagrams. The duals of the Archimedean solids are called the Catalan solids. In 2008 he lost to Deontay Wilder in a Duals. In electrical engineering, electrical terms are associated into pairs called duals.
