(145−13, 145, large)-Net over F₉ — Digital

Digital (132, 145, large)-net over F₉, using

t-expansion [i] based on digital (124, 145, large)-net over F₉, using
- Gilbertâ€“VarÅ¡amov bound [i]

(145−13, 145, large)-Net in Base 9 — Upper bound on s

There is no (132, 145, large)-net in base 9, because

11 times m-reduction [i] would yield (132, 134, large)-net in base 9, but
- mutually orthogonal hypercube bound [i]
