(169−120, 169, 1120)-Net in Base 8 — Upper bound on s

There is no (49, 169, 1121)-net in base 8, because

the generalized Rao bound for nets shows that 8^mÂ â‰¥ 420 647793 421637 597543 487565 866184 511529 308530 877488 686193 240991 535512 107547 107844 074750 549383 842248 540607 556492 523388 676601 126083 553095 517196 089897 667216 > 8¹⁶⁹ [i]
