(193−120, 193, 619)-Net in Base 4 — Upper bound on s

There is no (73, 193, 620)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 158 338387 706283 839879 140262 270618 951625 376912 962772 665983 745066 764850 497072 125868 580446 817279 091351 289613 971227 263760 > 4¹⁹³ [i]
