(103, 228, 216)-Net over F2 — Upper bound on s (digital)
There is no digital (103, 228, 217)-net over F2, because
- 21 times m-reduction [i] would yield digital (103, 207, 217)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2207, 217, F2, 104) (dual of [217, 10, 105]-code), but
- residual code [i] would yield linear OA(2103, 112, F2, 52) (dual of [112, 9, 53]-code), but
- residual code [i] would yield linear OA(251, 59, F2, 26) (dual of [59, 8, 27]-code), but
- adding a parity check bit [i] would yield linear OA(252, 60, F2, 27) (dual of [60, 8, 28]-code), but
- “BJV†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(252, 60, F2, 27) (dual of [60, 8, 28]-code), but
- residual code [i] would yield linear OA(251, 59, F2, 26) (dual of [59, 8, 27]-code), but

(103, 228, 217)-Net in Base 2 — Upper bound on s
There is no (103, 228, 218)-net in base 2, because
- 23 times m-reduction [i] would yield (103, 205, 218)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2205, 218, S2, 102), but
- the linear programming bound shows that M ≥ 272331 004236 659599 976647 399713 241508 574642 785762 357467 384194 793472 / 3835 > 2205 [i]
