(44−12, 44, 589605)-Net over F₄₉ — Digital

Digital (32, 44, 589605)-net over F₄₉, using

Gilbertâ€“VarÅ¡amov bound [i]

(44−12, 44, large)-Net in Base 49 — Upper bound on s

There is no (32, 44, large)-net in base 49, because

10 times m-reduction [i] would yield (32, 34, large)-net in base 49, but
- mutually orthogonal hypercube bound [i]
