Digital (174, 233, 1991)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(174, 233, 254941)-Net in Base 4 — Upper bound on s

There is no (174, 233, 254942)-net in base 4, because

1 times m-reduction [i] would yield (174, 232, 254942)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 47 637274 711154 986425 067347 845423 270813 530561 680484 777012 675398 643868 112871 177335 266425 494957 153568 927646 568383 374906 044452 383146 173049 468955 > 4²³² [i]
