  2. Mathematics of Sudoku - Wikipedia

    en.wikipedia.org/wiki/Mathematics_of_Sudoku

    The possible row (or column) permutations form a group isomorphic to S 3 ≀ S 3 of order 3! 4 = 1,296. [4] The whole rearrangement group is formed by letting the transposition operation (isomorphic to C 2) act on two copies of that group, one for the row permutations and one for the column permutations.

  3. Lottery mathematics - Wikipedia

    For a score of n (for example, if 3 choices match three of the 6 balls drawn, then n = 3), () describes the odds of selecting n winning numbers from the 6 winning numbers. This means that there are 6 - n losing numbers, which are chosen from the 43 losing numbers in () ways. The total number of combinations giving that result is, as stated ...

  4. Combination - Wikipedia

    en.wikipedia.org/wiki/Combination

    These combinations (subsets) are enumerated by the 1 digits of the set of base 2 numbers counting from 0 to 2 n − 1, where each digit position is an item from the set of n. Given 3 cards numbered 1 to 3, there are 8 distinct combinations , including the empty set:

  5. Shannon number - Wikipedia

    Claude Shannon. The Shannon number, named after the American mathematician Claude Shannon, is a conservative lower bound of the game-tree complexity of chess of 10 120, based on an average of about 10 3 possibilities for a pair of moves consisting of a move for White followed by a move for Black, and a typical game lasting about 40 such pairs of moves.

  6. Ternary numeral system - Wikipedia

    en.wikipedia.org/wiki/Ternary_numeral_system

    Use of ternary numbers to balance an unknown integer weight from 1 to 40 kg with weights of 1, 3, 9 and 27 kg (4 ternary digits actually gives 3 4 = 81 possible combinations: −40 to +40, but only the positive values are useful) In certain analog logic, the state of the circuit is often expressed ternary.

  7. Computer number format - Wikipedia

    en.wikipedia.org/wiki/Computer_number_format

    As the number of bits composing a string increases, the number of possible 0 and 1 combinations increases exponentially. A single bit allows only two value-combinations, two bits combined can make four separate values, three bits for eight, and so on, increasing with the formula 2 n. The amount of possible combinations doubles with each binary ...

  8. Truth table - Wikipedia

    en.wikipedia.org/wiki/Truth_table

    For instance, in an addition operation, one needs two operands, A and B. Each can have one of two values, zero or one. The number of combinations of these two values is 2×2, or four. So the result is four possible outputs of C and R. If one were to use base 3, the size would increase to 3×3, or nine possible outputs.

  9. Combinatorial number system - Wikipedia

    en.wikipedia.org/wiki/Combinatorial_number_system

    In mathematics, and in particular in combinatorics, the combinatorial number system of degree k (for some positive integer k), also referred to as combinadics, or the Macaulay representation of an integer, is a correspondence between natural numbers (taken to include 0) N and k - combinations. The combinations are represented as strictly ...
