PURPOSE:To omit the useless search and to improve the processing efficiency with a permutation generating device by producing two combinations of permutations having specific relation with preference when two combination of permutations are successively selected from (n) pieces of permuations. CONSTITUTION:The data groups (a, b, c, d, e, f) which form combinations are stored in registers 100-105. The contents of the register 100 or 101 are selected by a selector 109 and set to a register 108. A comparator 110 checks coincidence between the outputs of the register 108 and the selector 109. When the contents of the register 100 satisfy the necessary conditions, the contents of the register 101 are stored in the register 108 via the selector 109 by a command given from a control part 107. Then the contents of registers 101-105 are shifted with left rotations until the coincidence is obtained between the contents of registers 108 and 101. |
