| In this paper ,the knowledge of group theory and elementary number theory are combined densely in some degree .By analyzing the character of the defining relations of p-groups (p is an old prime )and automorphoism, using the method of solving equations of congruence ,we have worked out the order of automorphism ,groups of order p6 for isoclinic family from (φ11,φ33)..The result can be used in the research of automorphism, groups of p-groups furtherly. |
