    1994, James K. Strayer, Elementary Number Theory, Waveland Press, 2002, Reissue, page 109, Our only method at present for the computation of Legendre symbols requires a possible consideration of (p-1)/2 congruences (unless, of course, we are fortunate enough to encounter the desired quadratic residue along the way).

词源
