"WebIn number theory, Euler's criterion is a formula for determining whether an integer is a quadratic residue modulo a prime. Precisely, Let p be an odd prime and a be an integer coprime to p. Then [1] [2] [3] Euler's criterion can be concisely reformulated using the Legendre symbol: [4] The criterion first appeared in a 1748 paper by Leonhard Euler. " - Primality testing online
