(175−114, 175, 218)-Net over F3 — Upper bound on s (digital)
There is no digital (61, 175, 219)-net over F3, because
- extracting embedded orthogonal array [i] would yield linear OA(3175, 219, F3, 114) (dual of [219, 44, 115]-code), but
- residual code [i] would yield OA(361, 104, S3, 38), but
- the linear programming bound shows that M ≥ 215738 553867 294765 547315 427144 658478 953384 447876 816406 609237 390217 341335 785320 530901 097095 689610 364315 585436 148743 / 1 653900 488288 762417 441699 879030 043019 631369 903205 462657 103479 100855 831115 771782 746875 > 361 [i]
- residual code [i] would yield OA(361, 104, S3, 38), but
(175−114, 175, 269)-Net in Base 3 — Upper bound on s
There is no (61, 175, 270)-net in base 3, because
- the generalized Rao bound for nets shows that 3m ≥ 358898 103947 644432 548373 294490 567649 213348 676531 783733 401642 809217 677101 722149 735981 > 3175 [i]
