(132, 179, 1344)-Net over F₄ — Digital

Digital (132, 179, 1344)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(132, 179, 143449)-Net in Base 4 — Upper bound on s

There is no (132, 179, 143450)-net in base 4, because

1 times m-reduction [i] would yield (132, 178, 143450)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 146793 489752 181090 246694 966474 410780 773136 070872 101720 282999 246014 765440 409113 706102 114102 792716 745006 484836 > 4¹⁷⁸ [i]
