(203−99, 203, 233)-Net over F2 — Upper bound on s (digital)
There is no digital (104, 203, 234)-net over F2, because
- 1 times m-reduction [i] would yield digital (104, 202, 234)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2202, 234, F2, 98) (dual of [234, 32, 99]-code), but
- residual code [i] would yield OA(2104, 135, S2, 49), but
- 1 times truncation [i] would yield OA(2103, 134, S2, 48), but
- the linear programming bound shows that M ≥ 14817 140394 002966 911489 108655 371959 926784 / 1391 278625 > 2103 [i]
- 1 times truncation [i] would yield OA(2103, 134, S2, 48), but
- residual code [i] would yield OA(2104, 135, S2, 49), but
- extracting embedded orthogonal array [i] would yield linear OA(2202, 234, F2, 98) (dual of [234, 32, 99]-code), but
(203−99, 203, 266)-Net in Base 2 — Upper bound on s
There is no (104, 203, 267)-net in base 2, because
- 1 times m-reduction [i] would yield (104, 202, 267)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 7 002752 860830 517919 539481 172668 989636 712529 615994 155226 304832 > 2202 [i]
