(241−162, 241, 573)-Net in Base 4 — Upper bound on s

There is no (79, 241, 574)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12 568766 618880 996269 608098 741613 923089 192174 528817 833150 455838 170258 872880 975151 150906 396843 604254 666246 598957 617189 748476 745252 453533 687791 077880 > 4²⁴¹ [i]
