(125, 196, 404)-Net over F₄ — Digital

Digital (125, 196, 404)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(125, 196, 10454)-Net in Base 4 — Upper bound on s

There is no (125, 196, 10455)-net in base 4, because

1 times m-reduction [i] would yield (125, 195, 10455)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2528 889423 907318 708356 998559 666998 153859 090757 093592 506682 076371 514504 540773 502040 198514 192856 446627 727532 310064 793408 > 4¹⁹⁵ [i]
