Abstract

The purposes of this paper is the construction of some new extended generalized quadrangles, as covers of known esamples. The construction requires the vanishing of cohomology of certain simplicial complexes. One of the constructions generalizes to give some distance-regular antipodal covers of complete graphs, some of which also appear to be new.
