New binary one-generator quasi-cyclic codes

Sixteen new binary quasi-cyclic linear codes improving the best known lower bounds on minimum distance in Brouwer's tables are constructed. The parameters of these codes are 102, 26, 32], 102, 27, 30], 142, 35, 40], 142, 36, 38] 146, 36, 40], 170, 16, 72], 170, 20, 66], 170, 33, 52] 170, 36, 50], 178, 33, 56], 178, 34, 54], 182, 27, 64] 182, 36, 56], 186, 17, 76], 210, 23, 80], 254, 22, 102] Sixty cyclic and thirty quasi-cyclic codes, which attain the respective bounds in Brouwer's table and are not included in Chen's table are presented as well.
