(75, 75+150, 553)-Net in Base 4 — Upper bound on s

There is no (75, 225, 554)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3074 462057 761146 816430 371009 771938 721425 241816 667612 935617 877949 929903 054234 693391 253432 800380 756966 079584 018244 561410 353397 955906 120960 > 4²²⁵ [i]
