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 Tower purchased Hexagon Tower on behalf of a pension fund client. LaSalle has turned the facility into a multi-let science park, accommodating a range of tenants from SMEs such as Colour Synthesis Solutions to multi-national firms, including Intertek. The site now consists of 157,283 sq ft of machine halls, laboratories and office space over 13 floors and a lower ground level with multi-purpose laboratory space. Hexagon Tower received an International Standards Organisation certification for its environmental responsibility in January 2014. Hexagon Tower Hexagon Tower is a specialist science and technology facility located in Blackley, North Manchester, United Kingdom. The site is
