(200−126, 200, 609)-Net in Base 4 — Upper bound on s

There is no (74, 200, 610)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 590102 459107 264349 100379 422604 516688 069740 451906 465925 199487 220299 566238 091133 517006 817963 016368 810185 005073 406620 836640 > 4²⁰⁰ [i]
