With reference to James, Rodney, The groups of order (p^6) ((p) an odd prime)., Math. Comput. 34, 613-637 (1980). ZBL0428.20013., My question is can we get isoclinism class $\phi_2$ for a finite p-group of order $p^n$ ? Here, notation $ \phi_s(m_1,m_2...m_r)x_t $ denotes isoclinic class $\phi_2$ of type $(m_1,m_2...m_r)$ and $x_t$ denotes the genus of the group (defined in the article I have mentioned).
