(81, 112, 725)-Net over F₄ — Digital

Digital (81, 112, 725)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(81, 112, 61066)-Net in Base 4 — Upper bound on s

There is no (81, 112, 61067)-net in base 4, because

1 times m-reduction [i] would yield (81, 111, 61067)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 6 740589 552823 181026 339361 993229 140045 188211 193902 754972 280497 025792 > 4¹¹¹ [i]
