(246−150, 246, 843)-Net in Base 4 — Upper bound on s

There is no (96, 246, 844)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13115 079730 282355 500895 360954 509407 698846 760232 173047 319729 322406 969829 261808 878259 694583 124979 169730 854875 338704 799813 899210 103929 820691 051691 416587 > 4²⁴⁶ [i]
