(253−158, 253, 790)-Net in Base 4 — Upper bound on s

There is no (95, 253, 791)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 221 945907 059006 398652 549834 989419 799499 357971 199633 513220 902466 744830 784241 320843 451670 523541 384281 040421 973518 271888 598118 755158 767364 098491 293924 352288 > 4²⁵³ [i]
