This question was simply a result of my misreading the example on page 93, where it says "We first solve Pell's equation x2 􀀀 5y2 = 1 with d = 5 by nding the units of the ring of integers of Q(sqrt(5) using Sage." Of course I should have realized that just finding those units will give me th

I was not sure whether your question was mathematical or computational. Usually "Pell equation" means the +1 equation and ones says "negative Pell equation" for the -1 version. (I once wrote a paper "On the negative Pell equation"!). As Vincent says if you have a solution x+y*sqrt(d) to the nega

The VM reboots automatically when Sage quits. It seems to be quitting due to some error in your case. I'll add a check in the next version which should be out soon, please give it a try and report back. On Saturday, November 1, 2014 7:14:16 PM UTC, Christian M. wrote: > > I downloaded the Sage
