(243−124, 243, 1775)-Net in Base 4 — Upper bound on s

There is no (119, 243, 1776)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 202 262148 864628 317199 101041 076876 219135 548656 977057 059633 782303 591075 160587 402081 263911 641329 750213 418312 547633 148233 434484 997944 562467 513366 214100 > 4²⁴³ [i]
