(105, 160, 406)-Net over F₄ — Digital

Digital (105, 160, 406)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(105, 160, 12764)-Net in Base 4 — Upper bound on s

There is no (105, 160, 12765)-net in base 4, because

1 times m-reduction [i] would yield (105, 159, 12765)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 534603 374090 714999 071822 082072 529428 964283 769334 801865 457044 747848 951556 121934 784488 740948 707324 > 4¹⁵⁹ [i]
