International Standard Music Number 3 left to right. These weighted digits are added together. The check digit is the integer between 0 and 9 that makes the sum a multiple of 10. For instance, for the item with ISMN beginning 979-0-060-11561: As 85 mod 10 = 5, the check digit is 10 - 5 = 5 and the full number is 979-0-060-11561-5. For another example, Robert Fripp's collection of Guitar Craft scores has the ISMN 979-0-9016791-7-7. Given first 12 digits 979-0-9016791-7, the ISMN algorithm evaluates which implies that the check digit is indeed 7 (because 123+7=130=13x10).

Chess on a Really Big Board board for 3D chess would have 512 spaces, more than any large version of chess that had previously been invented; he then considered two-dimensional very large (or, in his word, "huge") chess games, mainly on the 16×16 board because such a board requires no non-standard equipment to construct, and while much larger than the 8×8 board, it was not so big as to make an unplayable game. This idea eventually came full circle in the development of the 16×16×16 three-dimensional version of Chess on a Really Big Board, which he called "impossibly large". The standard rules of chess apply, except
