3-5-8 3-5-8 3-5-8, also known as Sergeant Major for its popularity among members of Britain's Royal Air Force, is a trick-taking card game for 3 players, using a standard 52 card deck. 3-5-8 may be played as a gambling game, or not, and there are many variations with names like "8-5-3" and "9-5-2" played throughout the world. The version "9-5-3 variation with no kitty" was played in the Royal Navy over fifty years ago, when fellow crew would sit around to continue their game from the previous night. 3 players use a 52-card deck. The object is to win as many
Order-7-3 triangular honeycomb arrangement. It has a second construction as a uniform honeycomb, Schläfli symbol {6,(7,3,7)}, Coxeter diagram, , with alternating types or colors of cells. In Coxeter notation the half symmetry is [6,7,6,1] = [6,((7,3,7))]. In the geometry of hyperbolic 3-space, the order-7-infinite apeirogonal honeycomb (or ∞,7,∞ honeycomb) is a regular space-filling tessellation (or honeycomb) with Schläfli symbol {∞,7,∞}. It has infinitely many order-7 apeirogonal tiling {∞,7} around each edge. All vertices are ultra-ideal (existing beyond the ideal boundary) with infinitely many order-7 apeirogonal tilings existing around each vertex in an infinite-order heptagonal tiling vertex figure. It has a second construction as
