Title : Groebner bases for p-group algebras Author: David J. Green Date : 17 May 1999 Status: Submitted for publication Abstract: Experiment shows that the reverse length-lexicographical word ordering consistently yields far smaller Groebner bases for modular p-group algebras than the length-lexicographical ordering. For the so-called Jennings word ordering, based on a special power-conjugate group presentation, the associated monomial algebra is a group invariant. The package "Present" finds Groebner bases for these three orderings. Software: The package "Present" is available at http://www.math.uni-wuppertal.de/~green/software.html
