(77, 98, 1684)-Net over F7 — Constructive and digital
Digital (77, 98, 1684)-net over F7, using
- net defined by OOA [i] based on linear OOA(798, 1684, F7, 21, 21) (dual of [(1684, 21), 35266, 22]-NRT-code), using
- OOA 10-folding and stacking with additional row [i] based on linear OA(798, 16841, F7, 21) (dual of [16841, 16743, 22]-code), using
- discarding factors / shortening the dual code based on linear OA(798, 16845, F7, 21) (dual of [16845, 16747, 22]-code), using
- construction X applied to C([0,10]) ⊂ C([0,7]) [i] based on
- linear OA(791, 16808, F7, 21) (dual of [16808, 16717, 22]-code), using the expurgated narrow-sense BCH-code C(I) with length 16808 | 710−1, defining interval I = [0,10], and minimum distance d ≥ |{−10,−9,…,10}|+1 = 22 (BCH-bound) [i]

(77, 98, 19158)-Net over F7 — Digital
Digital (77, 98, 19158)-net over F7, using
(77, 98, large)-Net in Base 7 — Upper bound on s
There is no (77, 98, large)-net in base 7, because
- 19 times m-reduction [i] would yield (77, 79, large)-net in base 7, but
