I could have easily posted my query in the Homework Help
or Lounge forum, but elected this one because of the "GIMPS" umbrella, to which the relevance is obvious. Last fiddled with by davieddy on 20071211 at 03:12 Reason: Grammer (sic);)

We seek a k for which 1=nx  k(2p) for some n. We can do this because x and 2p are coprime (gcd=1). We use the Extended Euclid algorithm to do this, and needn't bother to find the corresponding n. David Last fiddled with by davieddy on 20071215 at 15:35

Ah no, I see, everyone ignore this while I go bury my head in the sand again. Last fiddled with by lavalamp on 20071216 at 13:17
