(42, 66, 300978)-Net over F₂₅₆ — Digital

Digital (42, 66, 300978)-net over F₂₅₆, using

Gilbertâ€“VarÅ¡amov bound [i]

(42, 66, large)-Net in Base 256 — Upper bound on s

There is no (42, 66, large)-net in base 256, because

22 times m-reduction [i] would yield (42, 44, large)-net in base 256, but
- mutually orthogonal hypercube bound [i]
