    Square the relation sq+rp=1. Mod pq inner terms cancel, and outer terms are invariant to signs of s and r. So the four square roots of unity mod pq are (+/-)(sq+rp) and (+/-)(sq-rp). This article is brought forward from a wiki page dated 2006/05/18 11:43.

  • Square roots Fp

    Let Y be the 2k roots of unity where p-1=2kj, j odd. Let y in Y be a quadratic non-residue, and hence a generator of Y. Let S0 by the stablized subgroup by repeated squarings of Fp. Let Si be those elements no in Si-1 but with squares in Si-1. Sk is the set of [...]
