Weight 1 for Fricke Groups Γ∗(q3p)
Here and in the following sections we will inspect eta products of some levels which have 8 or more positive divisors. A class of levels N with σ 0(N)=8 is given by N=q 3 p where q and p are distinct primes. Table 27.1 shows the numbers of new holomorphic eta products of weight 1 for some values of q and p. Since some of these numbers are quite large, we restrict our diligence to eta products for the Fricke groups.
