(121−56, 121, 120330)-Net in Base 16 — Upper bound on s

There is no (65, 121, 120331)-net in base 16, because

the generalized Rao bound for nets shows that 16^mÂ â‰¥ 49 950278 086344 692331 978676 154402 963407 111737 894571 179735 830012 914015 949981 173113 820185 614067 910404 813836 144054 590977 336897 233787 705315 082760 269696 > 16¹²¹ [i]
