(159−135, 159, 405)-Net over F8 — Upper bound on s (digital)
There is no digital (24, 159, 406)-net over F8, because
- 7 times m-reduction [i] would yield digital (24, 152, 406)-net over F8, but
- extracting embedded orthogonal array [i] would yield linear OA(8152, 406, F8, 128) (dual of [406, 254, 129]-code), but
- residual code [i] would yield OA(824, 277, S8, 16), but
- the linear programming bound shows that M ≥ 78638 403871 838919 782431 803777 157693 440000 / 16 504446 602386 301789 > 824 [i]
- residual code [i] would yield OA(824, 277, S8, 16), but
- extracting embedded orthogonal array [i] would yield linear OA(8152, 406, F8, 128) (dual of [406, 254, 129]-code), but
(159−135, 159, 449)-Net in Base 8 — Upper bound on s
There is no (24, 159, 450)-net in base 8, because
- 15 times m-reduction [i] would yield (24, 144, 450)-net in base 8, but
- the generalized Rao bound for nets shows that 8m ≥ 11170 651830 433015 653403 055602 867942 032543 601580 266295 219777 697700 093808 528299 244484 622191 586360 733694 092701 701151 245039 147744 656912 > 8144 [i]
