Here is the page's introduction written with math markup and so proper superscripts; but tex support is currently broken (at least for my [[Special:Preferences#prefsection-2|viewing preferences]]), so I haven't put it in yet. If you don't see errorsOnce belowfixed, copy it in (without the indent). --[[User:Kevin Reid|Kevin Reid]] 17:15, 28 July 2009 (UTC)
 
: Lucas-Lehmer Test: for <math>p</math> a prime, the Mersenne number <math>2^p-1</math> is prime if and only if <math>2^p-1</math> divides <math>S(p-1)</math> where <math>S(n+1)=S(n)^2-2</math>, and <math>S(1)=4</math>.
