A free group acting without fixed points on the rational unit sphere
A Note on the Discontinuous Subgroups of the Orthogonal Group.
A splitting theorem for linear polycyclic groups.
A transvection decomposition in GL(n,2)
An algorithm is given to decompose an automorphism of a finite vector space over ℤ₂ into a product of transvections. The procedure uses partitions of the indexing set of a redundant base. With respect to tents, i.e. finite ℤ₂-representations generated by a redundant base, this is a decomposition into base changes.
