(75, 75+180, 509)-Net in Base 4 — Upper bound on s

There is no (75, 255, 510)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3552 975203 801362 001954 461985 329100 262751 026387 008019 050880 418081 516763 887501 326656 295371 262373 320250 593017 550073 362340 560689 187166 054311 030017 742894 069442 > 4²⁵⁵ [i]
