We generalise the concept of universal central extensions for perfect groups to arbitrary finite groups. This construction, called the semiversal central extension of the group, has the property that it contains every cover of this group as a subquotient.
The quotient of a biautomatic group by a subgroup of the center is shown to be biautomatic. The main tool used is the Neumann-Shapiro triangulation of S, associated to a biautomatic structure on Zn. As an application, direct factors of biautomatic groups are shown to be biautomatic. Biautomatic groups form a wide class of finitely presented groups with interesting geometric and computational pr...
