(42, 58, 1923773)-Net over F₈₁ — Digital

Digital (42, 58, 1923773)-net over F₈₁, using

Gilbertâ€“VarÅ¡amov bound [i]

(42, 58, large)-Net in Base 81 — Upper bound on s

There is no (42, 58, large)-net in base 81, because

14 times m-reduction [i] would yield (42, 44, large)-net in base 81, but
- mutually orthogonal hypercube bound [i]
