Documentation Center page tutorial/SomeNotesOnInternalImplementation, which is on-line at http://reference.wolfram.com/mathematica/tutorial/SomeNotesOnInternalImplementation.html says merely: "The default pseudorandom number generator for functions like RandomReal and RandomInteger uses a cellular automaton-based algorithm."

Any one can help? Thanks. --- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
