The values of a(n) and the multiplicativity are conjectural.

Table of n, a(n) for n=1..78.

For example abs(A007653(n)) <= a(n) for all n where A007653 is the L-series for the curve y^2 - y = x^3 - x.

Sequence in context: A006047 A285712 A062068 * A128502 A244306 A079159

Adjacent sequences: A130539 A130540 A130541 * A130543 A130544 A130545
