A complete description of M (q) (g) is out of reach. So far, mostly bounds for the numbers N (q) (g):= maxM (q) (g) have been studied. In particular, Elkies et al. proved that there is a constant gamma (q) > 0 such that for any g a parts per thousand yen 0 there is some N a M (q) (g) with N a parts per thousand yen gamma (q) g. This implies that lim inf (g -> a) N (q) (g)/g > 0, and solves a long-standing problem by Serre. We extend the result of Elkies et al. substantially and show that there are constants alpha (q) , beta (q) > 0 such that for all g a parts per thousand yen 0, the whole interval [0, alpha (q) g - beta (q) ] a (c) a"center dot is contained in M (q) (g).
