(212−133, 212, 362)-Net over F3 — Upper bound on s (digital)
There is no digital (79, 212, 363)-net over F3, because
- 1 times m-reduction [i] would yield digital (79, 211, 363)-net over F3, but
- extracting embedded orthogonal array [i] would yield linear OA(3211, 363, F3, 132) (dual of [363, 152, 133]-code), but
- residual code [i] would yield OA(379, 230, S3, 44), but
- 2 times truncation [i] would yield OA(377, 228, S3, 42), but
- the linear programming bound shows that M ≥ 5912 215514 524704 110906 945136 883000 212719 987869 884535 855049 744419 389403 700722 336619 158801 044684 / 1072 032675 663595 149019 556086 689047 982002 296477 532875 566121 > 377 [i]
- 2 times truncation [i] would yield OA(377, 228, S3, 42), but
- residual code [i] would yield OA(379, 230, S3, 44), but
- extracting embedded orthogonal array [i] would yield linear OA(3211, 363, F3, 132) (dual of [363, 152, 133]-code), but
(212−133, 212, 364)-Net in Base 3 — Upper bound on s
There is no (79, 212, 365)-net in base 3, because
- 1 times m-reduction [i] would yield (79, 211, 365)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 51954 847099 737385 378336 455060 931607 559991 263664 518809 948792 206785 285144 079650 838704 621468 610287 455841 > 3211 [i]
