Practical methods for computing equivalent forms of integer matrices are presented. Both heuristic and modular techniques are used to overcome integer overflow problems, and have successfully handled matrices with hundreds of rows and columns. Applications to finding the structure of finitely presented abelian groups are described. 
Computing with Groups and Their Character Tables

Under suitable circumstances a finitely presented group can be shown to be soluble and its complete derived series can be determined, using what is in effect a soluble quotient algorithm. Expand
Recognizing badly presented Z-modules
Finitely generated Z-modules have canonical decompositions. When such modules are given in a finitely presented form, there is a classical algorithm for computing a canonical decomposition. This isExpand
Asymptotically fast triangulation of matrices over rings
TLDR
This paper shows how to apply fast matrix multiplication techniques to the problem of triangularizing a matrix over a ring using elementary column operations to lead to an algorithm for triangularizing integer matrices that has a faster running time than the known Hermite normal form algorithms.

Abelian actions on compact bordered Klein surfaces
We state necessary and sufficient conditions for a finite abelian group to act as a group of automorphisms of some compact bordered Klein surface of algebraic genus $$p>1$$p>1. This result provides aExpand
