(228−108, 228, 2390)-Net in Base 4 — Upper bound on s

There is no (120, 228, 2391)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 187941 620485 782749 027883 464688 465677 457480 499402 967358 840954 249215 801465 952526 275981 628863 545995 189865 731213 016038 513487 382846 629109 365146 > 4²²⁸ [i]
