(111−11, 111, large)-Net over F₉ — Digital

Digital (100, 111, large)-net over F₉, using

t-expansion [i] based on digital (95, 111, large)-net over F₉, using
- Gilbertâ€“VarÅ¡amov bound [i]

(111−11, 111, large)-Net in Base 9 — Upper bound on s

There is no (100, 111, large)-net in base 9, because

9 times m-reduction [i] would yield (100, 102, large)-net in base 9, but
- mutually orthogonal hypercube bound [i]
