(27, 27+91, 1562)-Net in Base 16 — Upper bound on s

There is no (27, 118, 1563)-net in base 16, because

1 times m-reduction [i] would yield (27, 117, 1563)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 764 492868 997578 029344 949127 142970 812835 032232 592099 911677 358100 290474 027069 160661 973961 996354 620511 393724 832957 805412 233893 992115 337532 187776 > 16¹¹⁷ [i]
