See the table on p. 217 of his paper. We use a(7) = 579150, which is a divisor of D_7 = 4054050. For an explanation of this change, see the comments for array A324124. (This modification does not change the values of the fractions gamma_r(n)/D_n used in Eq. (1) of Luke (1952). It is needed to give a unique definition of the terms of the array A324124.) %H A328866 Petros Hadjicostas, <a href="/A328866/a328866.txt">Maple program</a>. %H A328866 Yudell L.
