The Complete List of Maximal Cliques ofQuad(n,q),qEven

The graphQuad(n,q) has as its vertices all of the quadratic forms on a given vector space of dimensionnover the field ofqelements, with two vertices being adjacent if the rank of their difference is 1 or 2. The classification of the maximal cliques ofQuad(n,q), forqeven, is herein completed.
