(94, 94+49, 374)-Net over F₄ — Digital

Digital (94, 143, 374)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(94, 94+49, 11904)-Net in Base 4 — Upper bound on s

There is no (94, 143, 11905)-net in base 4, because

1 times m-reduction [i] would yield (94, 142, 11905)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 31 099827 090960 026290 194232 708447 368787 365833 062329 567104 040618 599561 829696 458870 144656 > 4¹⁴² [i]
