(42, 42+13, 10415)-Net over F₈ — Digital

Digital (42, 55, 10415)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(42, 42+13, large)-Net in Base 8 — Upper bound on s

There is no (42, 55, large)-net in base 8, because

11 times m-reduction [i] would yield (42, 44, large)-net in base 8, but
- mutually orthogonal hypercube bound [i]
