(139−84, 139, 2272)-Net in Base 8 — Upper bound on s

There is no (55, 139, 2273)-net in base 8, because

the generalized Rao bound for nets shows that 8^mÂ â‰¥ 342222 114089 802216 171447 899242 326675 720595 613124 014960 607135 868303 354612 023302 958391 088318 372288 192966 835341 599778 558665 116896 > 8¹³⁹ [i]
