I got lambda value searching... and found it in Hal Finney's post "Speeding up signature verification" ( https://bitcointalk.org/index.php?topic=3238.0 )
The lambda and beta values in that post are in hexadecimal.
lambda = 0x5363ad4cc05c30e0a5261c028812645a122e22ea20816678df02967c1b23bd72
beta = 0x7ae96a2b657c07106e64479eac3434e99cf0497512f58995c1396c28719501ee
