Best Known (42, 42+7, s)-Nets in Base 8
(42, 42+7, 2796200)-Net over F8 — Constructive and digital
Digital (42, 49, 2796200)-net over F8, using
- net defined by OOA [i] based on linear OOA(849, 2796200, F8, 7, 7) (dual of [(2796200, 7), 19573351, 8]-NRT-code), using
- OOA 3-folding and stacking with additional row [i] based on linear OA(849, 8388601, F8, 7) (dual of [8388601, 8388552, 8]-code), using
- discarding factors / shortening the dual code based on linear OA(849, large, F8, 7) (dual of [large, large−49, 8]-code), using
- the expurgated narrow-sense BCH-code C(I) with length 16777217 | 816−1, defining interval I = [0,3], and minimum distance d ≥ |{−3,−2,…,3}|+1 = 8 (BCH-bound) [i]
- discarding factors / shortening the dual code based on linear OA(849, large, F8, 7) (dual of [large, large−49, 8]-code), using
- OOA 3-folding and stacking with additional row [i] based on linear OA(849, 8388601, F8, 7) (dual of [8388601, 8388552, 8]-code), using
(42, 42+7, large)-Net over F8 — Digital
Digital (42, 49, large)-net over F8, using
(42, 42+7, large)-Net in Base 8 — Upper bound on s
There is no (42, 49, large)-net in base 8, because
- 5 times m-reduction [i] would yield (42, 44, large)-net in base 8, but
