Association schemes from the action of $P G L (2, q)$ fixing a nonsingular conic in PG(2,q)

Henk D. L. Hollmann, Qing Xiang

The group $P G L (2, q)$ has an embedding into $P G L (3, q)$ such that it acts as the group fixing a nonsingular conic in $P G (2, q)$ . This action affords a coherent configuration $R (q)$ on…

Pseudocyclic association schemes arising from the actions of PGL(2,2^m) and PΓL(2,2^m)

Henk D. L. Hollmann, Qing Xiang

The action of $P G L (2, 2^{m})$ on the set of exterior lines to a nonsingular conic in $P G (2, 2^{m})$ affords an association scheme, which was shown to be pseudocyclic in Hollmann's thesis…

Symmetric Bush-type Hadamard matrices of order $4 m^{4}$ exist for all odd $m$

Mikhail Muzychuk, Qing Xiang

Using reversible Hadamard difference sets, we construct symmetric Bush-type Hadamard matrices of order $4 m^{4}$ for all odd integer $m$ .
