(168−120, 168, 1081)-Net in Base 8 — Upper bound on s

There is no (48, 168, 1082)-net in base 8, because

the generalized Rao bound for nets shows that 8^mÂ â‰¥ 53 883828 384371 584922 591506 966033 560385 470956 073189 081554 813410 686435 118461 474974 773046 155187 536746 928694 892304 957600 441016 053543 407986 657457 163545 204992 > 8¹⁶⁸ [i]
