(91, 91+102, 1214)-Net in Base 4 — Upper bound on s

There is no (91, 193, 1215)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 158 247519 721412 837680 741149 810782 090196 414039 534817 908232 888552 374128 486440 828234 142531 958656 285180 950134 850248 444280 > 4¹⁹³ [i]
