(248−94, 248, 9161)-Net in Base 4 — Upper bound on s

There is no (154, 248, 9162)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 204833 342843 241984 565539 653594 763788 104080 300984 144866 144850 943678 587634 760789 222083 890163 744462 278016 272755 731351 637359 925254 266933 612153 022971 046240 > 4²⁴⁸ [i]
