(169−59, 169, 402)-Net over F₄ — Digital

Digital (110, 169, 402)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(169−59, 169, 11938)-Net in Base 4 — Upper bound on s

There is no (110, 169, 11939)-net in base 4, because

1 times m-reduction [i] would yield (110, 168, 11939)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 140271 896750 007911 430871 621947 205456 965772 911820 938293 349592 100662 966258 351373 537007 530079 794734 748080 > 4¹⁶⁸ [i]
