(117, 117+120, 246)-Net over F2 — Upper bound on s (digital)
There is no digital (117, 237, 247)-net over F2, because
- extracting embedded orthogonal array [i] would yield linear OA(2237, 247, F2, 120) (dual of [247, 10, 121]-code), but
- residual code [i] would yield linear OA(2117, 126, F2, 60) (dual of [126, 9, 61]-code), but
- residual code [i] would yield linear OA(257, 65, F2, 30) (dual of [65, 8, 31]-code), but
- 2 times truncation [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]
- 2 times truncation [i] would yield linear OA(255, 63, F2, 28) (dual of [63, 8, 29]-code), but
- residual code [i] would yield linear OA(257, 65, F2, 30) (dual of [65, 8, 31]-code), but
- residual code [i] would yield linear OA(2117, 126, F2, 60) (dual of [126, 9, 61]-code), but
(117, 117+120, 248)-Net in Base 2 — Upper bound on s
There is no (117, 237, 249)-net in base 2, because
- 14 times m-reduction [i] would yield (117, 223, 249)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2223, 249, S2, 106), but
- the linear programming bound shows that M ≥ 125060 361585 465082 046951 669439 069378 009061 149491 060510 099746 675837 762518 646784 / 7177 430007 > 2223 [i]
