An _updated_ version of the paper "How the Roll Function Works" is at http://www.sigapl.org/qqv8n3p42.htm .
It seems posterior to the version at http://www.jsoftware.com/jwiki/Doc/Articles/Play083. The section "Finding a Primitive Root" has been expanded quite a lot. I hope that is useful. ~ Gilles ---------- Original Message ----------- From: bill lam <[email protected]> To: JChat <[email protected]> Sent: Fri, 10 Apr 2009 21:35:58 +0800 Subject: [Jchat] Finding a Primitive Root > Inside > http://www.jsoftware.com/papers/roll.htm > > the paragraph: > > The way to proceed then is the following: for A and P positive > integers, A: P - 1 , where P is a prime and R is one of its primitive > roots, we get a vector called the indices of the powers of R mod P.
