 A010454 Squares mod 93. 1
 0, 1, 4, 7, 9, 10, 16, 18, 19, 25, 28, 31, 33, 36, 39, 40, 45, 49, 51, 63, 64, 66, 67, 69, 70, 72, 76, 78, 81, 82, 87, 90 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,3 LINKS EXAMPLE x^2 = 10 mod 93 has x = 14, 17, 76, 79 for solutions, hence 10 is in the sequence. x^2 = 11 mod 93 has no solutions, hence 11 is not in the sequence.
