(112, 177, 352)-Net over F₄ — Digital

Digital (112, 177, 352)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(112, 177, 8705)-Net in Base 4 — Upper bound on s

There is no (112, 177, 8706)-net in base 4, because

1 times m-reduction [i] would yield (112, 176, 8706)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 9195 282036 769701 058818 109868 255099 709408 140410 853507 862155 460379 785909 138184 192899 694015 565193 641532 745456 > 4¹⁷⁶ [i]
