satisfy some interesting identities but, unfortunately, these are not suitable for numerical
computations. Here we derive further identities, involving Dirichlet Lfunctions, that enable us
to compute numerically the values of C(q, a) with many digits for comparatively small q.
Details of these identities are given in §2, and the results of our … In this section we
concentrate on the numerical computation of the values of the constant C(q, a) for …
