形式，但也有相同数目的相同阶共轭循环子群。例如，除了上面提到的同一阶群中的一个以外，所有的情况都是这样的。因此，我们这里有不同群的系统，这些系统除了共形外，还有许多共同的性质。因此，可能的独立生成元集的算符的数目和形式被认为是对某些有限阶群系统的相当大的启发。
formal but have also the same number of conjugate cyclic subgroups of the same order. This is the case, for instance, as regards all except one of the (p 1)" 1 groups of the same order noted above. We have therefore here systems of distinct groups which have a large number of properties in common besides being conformal. The number and the form of the operators of possible sets of independent generators are thus seen to throw considerable light on certain systems of groups of finite orders.
