Curse of Scotland of 1715 and "became universally hated in Scotland". In 18th-century Scotland, the nine of diamonds was sometimes called the "Justice Clerk", and was considered to be the most unlucky card in the pack. James Mitchell's 1825 "Scotsman's Library" claimed that the expression originated from the Duke of Monmouth writing orders on such a card before the Battle of Bothwell Bridge (1679). Despite this, in "The Spectator", a reviewer of an 1885 book by George Gomme commented that the reviewer had believed that the phrase had started from an order written on a 9 by the Duke of Cumberland ("Butcher" Cumberland)
Ten of diamonds decahedron Ten of diamonds decahedron In geometry, the ten-of-diamonds decahedron is a space-filling polyhedron with 10 faces, 2 opposite rhombi with orthogonal major axes, connected by 8 identical isosceles triangle faces. Michael Goldberg references it by the playing card name, "ten-of-diamonds", as a 10-faced polyhedron with two opposite rhombic (diamond-shaped) faces. He catalogued it in a 1982 paper as 10-II, the second in a list of 26 known space-filling decahedra. If the space-filling polyhedron is placed in a 3-D coordinate grid, the coordinates for the 8 vertices can be given as: (0, ±2, −1), (±2, 0, 1), (±1, 0, −1), (0,
