(93, 93+148, 804)-Net in Base 4 — Upper bound on s

There is no (93, 241, 805)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12 906277 983579 396017 787090 298274 564064 887818 348150 528614 882837 666677 722014 956245 458746 171043 999649 834116 366922 615576 186252 586704 172857 191934 292128 > 4²⁴¹ [i]
