(33, 46, 1368146)-Net over F₈₁ — Digital

Digital (33, 46, 1368146)-net over F₈₁, using

Gilbertâ€“VarÅ¡amov bound [i]

(33, 46, large)-Net in Base 81 — Upper bound on s

There is no (33, 46, large)-net in base 81, because

11 times m-reduction [i] would yield (33, 35, large)-net in base 81, but
- mutually orthogonal hypercube bound [i]
