Regular permutation group 正则置换群
With each recursive step , cross products with one additional permutation group are formed 伴随每个递回步骤,会形成带有一个额外置换群的向量积。
4 . according to the property that all states of a certain cellular automata can build a permutation group , we can design block cipher based on this property 根据有些细胞自动机的所有状态可以构成一个循环群这一特点,指出了利用细胞自动机构造分组密码的方式。
In mathematics, a permutation group is a group G whose elements are permutations of a given set M, and whose group operation is the composition of permutations in G (which are thought of as bijective functions from the set M to itself); the relationship is often written as (G,M). Note that the group of all permutations of a set is the symmetric group; the term permutation group is usually restricted to mean a subgroup of the symmetric group.
