[seqfan] Re: Is this constant already in the OEIS?

[Juan Arias de Reyna]

Dear sequence fans:

Jan van de Lune and I computed to high precision this constant:

J. A de R and J. van de Lune, "High precision computation of a constant
in the Theory of trigonometric series, Math of Comp. 268 (2009)2187--2191.

In the paper we include it with 1120 digits. In OEIS it is included as 
A157957 <http://oeis.org/A157957>, where it is called Littlewood-Salem-Izumi constant.

Best regards, 
Juan Arias de Reyna
