(237−126, 237, 232)-Net over F2 — Upper bound on s (digital)
There is no digital (111, 237, 233)-net over F2, because
- 14 times m-reduction [i] would yield digital (111, 223, 233)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2223, 233, F2, 112) (dual of [233, 10, 113]-code), but
- residual code [i] would yield linear OA(2111, 120, F2, 56) (dual of [120, 9, 57]-code), but
- residual code [i] would yield linear OA(255, 63, F2, 28) (dual of [63, 8, 29]-code), but
- “BJV†bound on codes from Brouwer’s database [i]
- residual code [i] would yield linear OA(255, 63, F2, 28) (dual of [63, 8, 29]-code), but
- residual code [i] would yield linear OA(2111, 120, F2, 56) (dual of [120, 9, 57]-code), but
- extracting embedded orthogonal array [i] would yield linear OA(2223, 233, F2, 112) (dual of [233, 10, 113]-code), but
(237−126, 237, 234)-Net in Base 2 — Upper bound on s
There is no (111, 237, 235)-net in base 2, because
- 22 times m-reduction [i] would yield (111, 215, 235)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2215, 235, S2, 104), but
- the linear programming bound shows that M ≥ 8195 823786 813794 497578 772586 453967 724785 691904 452334 034255 497515 761664 / 117183 > 2215 [i]
- extracting embedded orthogonal array [i] would yield OA(2215, 235, S2, 104), but
