(99, 156, 321)-Net over F₄ — Digital

Digital (99, 156, 321)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(99, 156, 8081)-Net in Base 4 — Upper bound on s

There is no (99, 156, 8082)-net in base 4, because

1 times m-reduction [i] would yield (99, 155, 8082)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2089 544879 087020 189014 171623 588625 492120 068569 277890 801709 073316 430979 199305 043973 742274 289824 > 4¹⁵⁵ [i]
