Isotoxal figure 2-dimensional tessellation constructed from regular polygons is isotoxal. For instance, the truncated icosahedron (the familiar soccerball) has two types of edges: hexagon-hexagon and hexagon-pentagon, and it is not possible for a symmetry of the solid to move a hexagon-hexagon edge onto a hexagon-pentagon edge. An isotoxal polyhedron has the same dihedral angle for all edges. There are nine convex isotoxal polyhedra formed from the Platonic solids, 8 formed by the Kepler–Poinsot polyhedra, and six more as quasiregular (3 | p q) star polyhedra and their duals. There are at least 5 polygonal tilings of the Euclidean plane that are isotoxal,
Hexagon Sun released songs with the title "Turquoise Hexagon Sun" and "Orange Hexagon Sun"; the former has been featured on "Boc Maxima", "Hi Scores", and "Music Has the Right to Children", and the latter on the bootleg "Old Tunes, Vol. 2" tape. The existence of Hexagon Sun and oblique references to it in interviews, web sites and album packaging have contributed to what many people regard as the mythological aura surrounding Boards of Canada. Opinions on this subject differ greatly; certain fans of Boards of Canada and their record label Warp regard Hexagon Sun as a mysterious cult, while others believe that
