WebWe also exhibit one more globally irreducible representation, which is related to the Weil representation of degree (pn-1)/2 of the symplectic group Sp2n(p) (p ≡ 1 (mod 4) is a prime). As a consequence, we get a new series of even unimodular lattices of rank 2(pn−1). A summary of currently known globally irreducible representations is given.
