(43, 68, 255970)-Net over F₂₅₆ — Digital

Digital (43, 68, 255970)-net over F₂₅₆, using

Gilbertâ€“VarÅ¡amov bound [i]

(43, 68, large)-Net in Base 256 — Upper bound on s

There is no (43, 68, large)-net in base 256, because

23 times m-reduction [i] would yield (43, 45, large)-net in base 256, but
- mutually orthogonal hypercube bound [i]
