Abstract

In this paper we describe an infinite family of Cameron-Liebler line classes of \rm PG(3,q) with parameter (q² + 1)/2, q≡ 1\pmod4. The example obtained admits \rm PGL(2,q) as an automorphism group and it is shown to be isomorphic to none of the infinite families known so far whenever q ≥ 9.
