1 Introduction

SglPPow is a package which extends the Small Groups Library. Currently the Small Groups Library gives access to the following groups:

(1)

Those of order at most 2000 except 1024 (423,164,062 groups);

(2)

Those of cubefree order at most 50,000 (395,703 groups);

(3)

Those of order p⁷ for the primes p=3,5,7,11 (907,489 groups);

(4)

Those of order pⁿ for n ≤ 6 and all primes p;

(5)

Those of order pqⁿ where qⁿ divides 28, 36, 55 or 74 and p is an arbitrary prime not equal to q;

(6)

Those of squarefree order;

(7)

Those whose order factorizes into at most 3 primes.

This package gives access to the groups of order p⁷ for primes p > 11, and to the groups of order 3⁸.

To access the groups of order p⁷ for primes p > 11 you need the packages LiePRing (by Michael Vaughan-Lee and Bettina Eick) and LieRing (by Willem de Graaf and Serena Cicalo).

The groups of order 3⁸ have been determined by Michael Vaughan-Lee. The groups of order p⁷ for primes p > 11 are available via the database of the nilpotent Lie rings of order p^k for k ≤ 7 and primes p > 3 in the LiePRing package. These groups are obtained from the Lie rings using the implementation of the Baker-Campbell-Hausdorff formula in the LieRing package.
