(182, 182+43, 3281)-Net over F3 — Digital
Digital (182, 225, 3281)-net over F3, using
- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OOA(3225, 3281, F3, 2, 43) (dual of [(3281, 2), 6337, 44]-NRT-code), using
- OOA 2-folding [i] based on linear OA(3225, 6562, F3, 43) (dual of [6562, 6337, 44]-code), using
- the expurgated narrow-sense BCH-code C(I) with length 6562 | 316−1, defining interval I = [0,21], and minimum distance d ≥ |{−21,−20,…,21}|+1 = 44 (BCH-bound) [i]
- OOA 2-folding [i] based on linear OA(3225, 6562, F3, 43) (dual of [6562, 6337, 44]-code), using
(182, 182+43, 533014)-Net in Base 3 — Upper bound on s
There is no (182, 225, 533015)-net in base 3, because
- 1 times m-reduction [i] would yield (182, 224, 533015)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 75017 882775 483375 805148 147918 513975 956061 513262 456521 076298 955199 315245 664810 059276 682130 586852 395683 426759 > 3224 [i]
