(21−18, 21, 56)-Net over F27 — Digital
Digital (3, 21, 56)-net over F27, using
- net from sequence [i] based on digital (3, 55)-sequence over F27, using

(21−18, 21, 344)-Net in Base 27 — Upper bound on s
There is no (3, 21, 345)-net in base 27, because
- the generalized Rao bound for nets shows that 27m ≥ 1 159173 133361 783982 985088 869675 > 2721 [i]
