(16−9, 16, 137)-Net over F25 — Digital
Digital (7, 16, 137)-net over F25, using
- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OA(2516, 137, F25, 9) (dual of [137, 121, 10]-code), using
- discarding factors / shortening the dual code based on linear OA(2516, 208, F25, 9) (dual of [208, 192, 10]-code), using
(16−9, 16, 16109)-Net in Base 25 — Upper bound on s
There is no (7, 16, 16110)-net in base 25, because
- 1 times m-reduction [i] would yield (7, 15, 16110)-net in base 25, but
- the generalized Rao bound for nets shows that 25m ≥ 931 527310 479147 576001 > 2515 [i]
