Hexagon has no degrees of freedom but can seen as directed edges. Hexagons of symmetry g2, i4, and r12, as parallelogons can tessellate the Euclidean plane by translation. Other hexagon shapes can tile the plane with different orientations. The 6 roots of the simple Lie group , represented by a Dynkin diagram , are in a regular hexagonal pattern. The two simple roots have a 120° angle between them. The 12 roots of the Exceptional Lie group G2, represented by a Dynkin diagram are also in a hexagonal pattern. The two simple roots of two lengths have a 150° angle between
Super Hexagon Super Hexagon Super Hexagon is an independent twitch video game developed by Terry Cavanagh, with music composed by Chipzel. Originally released for iOS in September 2012, versions for Windows and macOS were released 3 months later, and Android, BlackBerry and Linux versions followed in early 2013. The game is based on an earlier prototype by Cavanagh, simply titled Hexagon, which was created for a twelve-hour game jam in early 2012. "Super Hexagon" is a fast-paced twitch game in which the player controls a triangle on a hexagonal grid in the center while walls come from the edges of the screen.
