组构造器¶ sympy.combinatorics.group_constructs.DirectProduct(*groups)[源代码][源代码]¶ 返回几个群的直积,作为一个置换群。 参见 sympy.combinatorics.perm_groups.PermutationGroup.__mul__ 示例 >>> from sympy.combinatorics.group_constructs import DirectProduct >>> from sympy.combinatorics.named_groups import CyclicGroup >>> C = CyclicGroup(4) >>> G = DirectProduct(C, C, C) >>> G.order() 64
