Title
A four-class association scheme
Abstract
Abstract: We show the existence of a four-class association scheme defined on the unordered pairs of distinct points from PG(1, q²), for q >= 4 a power of 2, thereby proving a conjecture of De Caen and Van Dam [2]. This is a fusion of certain relations in the fission scheme FT (q² + 1) obtained from the triangular association scheme (see [2]). Combining three relations in the above four...
