(28, 39, 695)-Net over F5 — Digital
Digital (28, 39, 695)-net over F5, using
- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OA(539, 695, F5, 11) (dual of [695, 656, 12]-code), using
- 63 step Varšamov–Edel lengthening with (ri) = (2, 1, 0, 0, 1, 7 times 0, 1, 16 times 0, 1, 33 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]
- 63 step Varšamov–Edel lengthening with (ri) = (2, 1, 0, 0, 1, 7 times 0, 1, 16 times 0, 1, 33 times 0) [i] based on linear OA(533, 626, F5, 11) (dual of [626, 593, 12]-code), using
(28, 39, 133640)-Net in Base 5 — Upper bound on s
There is no (28, 39, 133641)-net in base 5, because
- 1 times m-reduction [i] would yield (28, 38, 133641)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 363 806203 870746 568500 160597 > 538 [i]
