(243−116, 243, 2444)-Net in Base 4 — Upper bound on s

There is no (127, 243, 2445)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 202 562536 249076 455508 745672 849965 693472 596057 852062 258814 282280 484838 319327 294555 768109 888350 070448 792884 116933 671401 331126 156765 365837 210423 279504 > 4²⁴³ [i]
