(42, 42+12, large)-Net over F₄₉ — Digital

Digital (42, 54, large)-net over F₄₉, using

49² times duplication [i] based on digital (40, 52, large)-net over F₄₉, using
- Gilbertâ€“VarÅ¡amov bound [i]

(42, 42+12, large)-Net in Base 49 — Upper bound on s

There is no (42, 54, large)-net in base 49, because

10 times m-reduction [i] would yield (42, 44, large)-net in base 49, but
- mutually orthogonal hypercube bound [i]
