(197−90, 197, 2502)-Net in Base 4 — Upper bound on s

There is no (107, 197, 2503)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 40605 578963 505756 742255 908369 850212 503274 717274 435354 304225 090944 601020 956962 225010 671128 061092 146199 497840 098950 078384 > 4¹⁹⁷ [i]
