The automorphism group and the convex subgraphs of the quadratic forms graph in characteristic 2
We determine the automorphism group and the convex subgraphs of the quadratic forms graph Quad(n,q),q even.
Projective covering designs
A (2, k, v) covering design is a pair (X, F) such that X is a v-element set and F is a family of k-element subsets, called blocks, of X with the property that every pair of distinct elements of X is contained in at least ...
