(44, 44+16, 3456350)-Net over F₈₁ — Digital

Digital (44, 60, 3456350)-net over F₈₁, using

Gilbertâ€“VarÅ¡amov bound [i]

(44, 44+16, large)-Net in Base 81 — Upper bound on s

There is no (44, 60, large)-net in base 81, because

14 times m-reduction [i] would yield (44, 46, large)-net in base 81, but
- mutually orthogonal hypercube bound [i]
