 Abstract: A combinatorial formulation for Steenrod squares is given
in [Gonzalez-Diaz R. and Real P. : ``A combinatorial method for
computing Steenrod squares''. To appear in Journal of Pure and Applied
Algebra (June, 1999) ] .  This computer algebra tool is used here in
order to derive several results concerning the action of the Steenrod
algebra on the cohomology of polyhedral simplicial sets.
