More terms from ZQ Bai (phybai(AT)163.com), Dec 17 2007

3 additional terms (computed directly from D. Viswanath program using 2^32 subdivisions, 128 bits double and Wynn epsilon extrapolation) by Jerome Raulin, Oct 13 2017

The proposed last three digits (061 of 1.1319882487943061) have been deleted as there seems to be some doubt about them. - N. J. A. Sloane, Feb 25 2018
