(89−19, 89, 2570142)-Net over F₂₅ — Digital

Digital (70, 89, 2570142)-net over F₂₅, using

Gilbertâ€“VarÅ¡amov bound [i]

(89−19, 89, large)-Net in Base 25 — Upper bound on s

There is no (70, 89, large)-net in base 25, because

17 times m-reduction [i] would yield (70, 72, large)-net in base 25, but
- mutually orthogonal hypercube bound [i]
