(24−13, 24, 345)-Net over F49 — Digital
Digital (11, 24, 345)-net over F49, using
- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OA(4924, 345, F49, 13) (dual of [345, 321, 14]-code), using
- discarding factors / shortening the dual code based on linear OA(4924, 480, F49, 13) (dual of [480, 456, 14]-code), using
- the expurgated narrow-sense BCH-code C(I) with length 480 | 492−1, defining interval I = [0,12], and designed minimum distance d ≥ |I|+1 = 14 [i]
- discarding factors / shortening the dual code based on linear OA(4924, 480, F49, 13) (dual of [480, 456, 14]-code), using
(24−13, 24, 187957)-Net in Base 49 — Upper bound on s
There is no (11, 24, 187958)-net in base 49, because
- 1 times m-reduction [i] would yield (11, 23, 187958)-net in base 49, but
- the generalized Rao bound for nets shows that 49m ≥ 749 059317 271514 352707 078751 578918 361025 > 4923 [i]
