(27, 38, 660)-Net over F5 — Digital
Digital (27, 38, 660)-net over F5, using
- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OA(538, 660, F5, 11) (dual of [660, 622, 12]-code), using
- 29 step Varšamov–Edel lengthening with (ri) = (2, 1, 0, 0, 1, 7 times 0, 1, 16 times 0) [i] based on linear OA(533, 626, F5, 11) (dual of [626, 593, 12]-code), using
- the expurgated narrow-sense BCH-code C(I) with length 626 | 58−1, defining interval I = [0,5], and minimum distance d ≥ |{−5,−4,…,5}|+1 = 12 (BCH-bound) [i]
- 29 step Varšamov–Edel lengthening with (ri) = (2, 1, 0, 0, 1, 7 times 0, 1, 16 times 0) [i] based on linear OA(533, 626, F5, 11) (dual of [626, 593, 12]-code), using
(27, 38, 96858)-Net in Base 5 — Upper bound on s
There is no (27, 38, 96859)-net in base 5, because
- 1 times m-reduction [i] would yield (27, 37, 96859)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 72 759796 313434 262275 494749 > 537 [i]
