Abstract
Let Ω denote the set of two-element subsets of the projective line PG(1, q), where q = 2e, e > 1. The character table of the association scheme X (PGL(2, q), Ω) is calculated. Then by using this character table, we prove that the conjectured subscheme of de Caen and van Dam is indeed an association scheme.
