Streszczenie
An algorithm is given to decompose an automorphism of a finite vector space over ${\mathbb Z}_{2}$ into a product of transvections. The procedure uses partitions of the indexing set of a redundant base. With respect to tents, i.e. finite ${\mathbb Z}_{2}$-representations generated by a redundant base, this is a decomposition into base changes.
