Minimal degrees for faithful permutation representations of groups of order $p^{6}$ where $p$ is an odd prime

E. A. O'Brien, Sunil Kumar Prajapati, Ayush Udeep

We determine the minimal degree of a faithful permutation representation for each group of order $p^{6}$ where $p$ is an odd prime. We also record how to obtain such a representation…

Isomorphism invariant metrics

P. A. Brooksbank, J. F. Maglione, E. A. O'Brien +1

Within a category $C$ , having objects $C_{0}$ , it may be instructive to know not only that two objects are non-isomorphic, but also how far from being isomorphic th…

M. F. Newman, E. A. O'Brien, M. R. Vaughan-Lee

We list those presentations for the groups of order $p^{6}$ for prime $p \geq 7$ which are distributed as part of the {\sc SmallGroups} library.
