| The smallest known sides of simple perfect squared squares (and the known orders of the squares) are 110 (22, 23), 112 (21), 120 (24), 139 (22, 23), 140 (23), 145 (23), 147 (22, 25) ...
Upper bounds for terms a(30) to a(78);

a(30) <= 237, a(31) <= 236,
a(32) <= 414, a(33) <= 499, a(34) <= 389, a(35) <= 480, a(36) <= 448, a(37) <= 476,
a(38) <= 550, a(39) <= 360, a(40) <= 510, a(41) <= 557, a(42) <= 501, a(43) <= 604,
a(44) <= 623, a(45) <= 543, a(46) <= 601, a(47) <= 691, a(48) <= 621, a(49) <= 779,
