ecpp_disc_struct

A discriminant of the pool: D, the class number h, the number g of genus characters, the odd part o = h/2^{g-1} of the class number, the factor q0 \in \{1, -4, 8, -8\} of D at 2 (so that D = q_0 \prod p^*), the number nfac of odd primes dividing D with their indices fac in the prime list, and the estimated cost cost.
