(119, 190, 352)-Net over F₄ — Digital

Digital (119, 190, 352)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(119, 190, 8236)-Net in Base 4 — Upper bound on s

There is no (119, 190, 8237)-net in base 4, because

1 times m-reduction [i] would yield (119, 189, 8237)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 616122 786836 102712 376678 401057 415479 259174 363203 505524 875649 011371 910804 021045 757435 125915 850193 561842 868112 311228 > 4¹⁸⁹ [i]
