(229−118, 229, 1603)-Net in Base 4 — Upper bound on s

There is no (111, 229, 1604)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 745926 096346 838196 823044 824949 184378 609348 387005 744220 035846 132591 290652 382970 449561 550477 277627 196428 889009 720099 865715 505624 529477 532136 > 4²²⁹ [i]
