When I found in Edouard Lucas' Wikipedia page that he proved that $2^{127}-1$ is prime by hand, I wanted to see how did he do it. Unfortunately, every piece of information I find is about the Lucas-Lehmer test, that is a version of his test refined by Lehmer.

Since I wanted to do some comparisons about how many it would take to do so with a computer and a high-school multiplication algorithm (according to Wikipedia it took him $19$ years by hand) the Lucas-Lehmer test is not exactly what I am looking for. So, finally, where can I find the original test?

  • Thank you for the references, but since I don't speak French it is a little hard to me to understand his paper. Not impossible, given the similarity with my native language, but a little painful. Is there an english version? – chubakueno Sep 30 '13 at 02:45
  • Not that I know of. – Daniel McLaury Sep 30 '13 at 02:49
