Best Known (121−18, 121, s)-Nets in Base 8
(121−18, 121, 932067)-Net over F8 — Constructive and digital
Digital (103, 121, 932067)-net over F8, using
- net defined by OOA [i] based on linear OOA(8121, 932067, F8, 18, 18) (dual of [(932067, 18), 16777085, 19]-NRT-code), using
- OA 9-folding and stacking [i] based on linear OA(8121, large, F8, 18) (dual of [large, large−121, 19]-code), using
- the primitive expurgated narrow-sense BCH-code C(I) with length 16777215 = 88−1, defining interval I = [0,17], and designed minimum distance d ≥ |I|+1 = 19 [i]

(121−18, 121, 5762552)-Net over F8 — Digital
Digital (103, 121, 5762552)-net over F8, using
- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OA(8121, 5762552, F8, 18) (dual of [5762552, 5762431, 19]-code), using
- discarding factors / shortening the dual code based on linear OA(8121, large, F8, 18) (dual of [large, large−121, 19]-code), using
- the primitive expurgated narrow-sense BCH-code C(I) with length 16777215 = 88−1, defining interval I = [0,17], and designed minimum distance d ≥ |I|+1 = 19 [i]

(121−18, 121, large)-Net in Base 8 — Upper bound on s
There is no (103, 121, large)-net in base 8, because
- 16 times m-reduction [i] would yield (103, 105, large)-net in base 8, but
