(69−18, 69, large)-Net over F128 — Digital
Digital (51, 69, large)-net over F128, using
- 1 times m-reduction [i] based on digital (51, 70, large)-net over F128, using
(69−18, 69, large)-Net in Base 128 — Upper bound on s
There is no (51, 69, large)-net in base 128, because
- 16 times m-reduction [i] would yield (51, 53, large)-net in base 128, but
