(19, 19+23, 762)-Net over F₁₂₈ — Digital

Digital (19, 42, 762)-net over F₁₂₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(19, 19+23, 2762840)-Net in Base 128 — Upper bound on s

There is no (19, 42, 2762841)-net in base 128, because

1 times m-reduction [i] would yield (19, 41, 2762841)-net in base 128, but
- the generalized Rao bound for nets shows that 128^mÂ â‰¥ 248 661656 368891 246399 973930 770181 891108 077758 732812 767882 513913 287141 308039 207517 051056 > 128⁴¹ [i]
