(118, 179, 461)-Net over F₄ — Digital

Digital (118, 179, 461)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(118, 179, 14968)-Net in Base 4 — Upper bound on s

There is no (118, 179, 14969)-net in base 4, because

1 times m-reduction [i] would yield (118, 178, 14969)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 146911 205442 028669 597225 865577 638999 585252 239874 864490 717300 274842 005492 010474 079953 999036 451674 297871 959664 > 4¹⁷⁸ [i]
