(186−72, 186, 6111)-Net in Base 4 — Upper bound on s

There is no (114, 186, 6112)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 9628 804453 820320 358562 197407 209020 839586 698331 704499 069191 867599 003692 894958 286881 133634 115244 964929 819411 079446 > 4¹⁸⁶ [i]
