(23, 23+13, 87341)-Net over F₁₂₈ — Digital

Digital (23, 36, 87341)-net over F₁₂₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(23, 23+13, large)-Net in Base 128 — Upper bound on s

There is no (23, 36, large)-net in base 128, because

11 times m-reduction [i] would yield (23, 25, large)-net in base 128, but
- mutually orthogonal hypercube bound [i]
