The last line should read "if a= 1 (mod 4) there is no analogous formula." That's true, but in that case you would use the Shanks-Tonelli algorithm. Maybe you should provide a link to it! Just my two cents. Otherwise a nice, complete and informative post - as your always are. I enjoy them. cheers, Alasdair This post just got tweeted as as an “Algebra Fact”.
