(97, 107, large)-Net over F9 — Digital
Digital (97, 107, large)-net over F9, using
- t-expansion [i] based on digital (95, 107, large)-net over F9, using

(97, 107, large)-Net in Base 9 — Upper bound on s
There is no (97, 107, large)-net in base 9, because
- 8 times m-reduction [i] would yield (97, 99, large)-net in base 9, but
