But there are also ranges for which conclusive searching is not yet finished. The 'false' and 'FAIL' returns from numtheory:-mersenne do not reflect all that.</p> <p>The numtheory package was updated as a module, and the list now appears to be stored in a name (w) accessed by numtheory:-mersenne via lexical scoping. In case anyone's interested in seeing Maple's internal list, here's how to show it in Maple 12.</p> <pre> eval([op(7,eval(numtheory:-mersenne))][2]); </pre> <p>acer</p> The latest comments added to the Post, "New" Mersenne Primes 69598 Mon, 29 Sep 2008 20:17:58 Z acer acer
