(92, 143, 324)-Net over F₄ — Digital

Digital (92, 143, 324)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(92, 143, 8896)-Net in Base 4 — Upper bound on s

There is no (92, 143, 8897)-net in base 4, because

1 times m-reduction [i] would yield (92, 142, 8897)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 31 134291 410973 136474 425783 242951 868021 195493 360171 189528 778852 583568 019226 367769 850784 > 4¹⁴² [i]
