(186−80, 186, 3280)-Net in Base 4 — Upper bound on s

There is no (106, 186, 3281)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 9677 902408 065114 857845 990050 023261 647312 426056 259231 614187 856364 141494 891677 075435 794889 254424 817351 067441 653596 > 4¹⁸⁶ [i]
