Square dance square dance, very rarely are two modern Western dances ever alike. Like traditional square dancing, recovering from occasional mistakes is often part of the fun. Dancers are encouraged to dance only those programs at which they are reasonably proficient, the default level of achievement being the Mainstream program. All programs are set by Callerlab, the callers' international association, which also governs the training of callers. Irish and Scottish dances are normally done to traditional tunes. English dances may be done to traditional tunes, though, especially at ceilidhs, there is experimentation with many different musical styles. The two types of American
Order-4 square tiling honeycomb Order-4 square tiling honeycomb In the geometry of hyperbolic 3-space, the order-4 square tiling honeycomb, is one of 11 paracompact regular honeycombs. It is called "paracompact" because it has infinite cells and vertex figures, with all vertices as ideal points at infinity. Given by Schläfli symbol {4,4,4}, has four square tilings, {4,4} around each edge, and infinite square tilings around each vertex in an square tiling {4,4} vertex arrangement. It has many reflective symmetry constructions, as a regular honeycomb, ↔ with alternate types (colors) of square tilings, and with 3 types (colors) of square tilings, with a ratio of 2:1:1.
