D is an incidence matrix of the structure S). t C 1/I , where A is an adjacency matrix of the point graph of S (cf. 2). s C t /. , rij D 0) otherwise. Then Q and R are permutation matrices for which DR D QD. Q 1 /T D DD T Q D MQ. Hence QM D MQ. 1 (C. T. Benson [10], cf. also [142]). mod s C t /: Proof. QM /n D Qn M n D M n . It follows that the eigenvalues of QM are the eigenvalues of M multiplied by the appropriate roots of 20 Chapter 1. Combinatorics of finite generalized quadrangles unity.

Fx; yg?? /, then u is on just one line joining a point of fx; yg? to a point of fx; yg?? ; if u 2 fx; yg? [ fx; yg?? , then u is on s C 1 lines joining a point of fx; yg? to a point of fx; yg?? L; u/, with L a line joining a point of fx; yg? to a point of fx; yg?? and with u a point of O which is incident with L. 1 C s/. Hence r D 2. Since no two points of O are collinear, there follows jO \ fx; yg?? j; jO \ fx; yg? j 2 f0; 2g. Let O be an ovoid of the GQ S of order s and let z be a regular point not on O.
