(49, 47)-Sequence over F3 — Constructive and digital
Digital (49, 47)-sequence over F3, using
- t-expansion [i] based on digital (45, 47)-sequence over F3, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F3 with g(F) = 45 and N(F) ≥ 48, using
(49, 63)-Sequence over F3 — Digital
Digital (49, 63)-sequence over F3, using

(49, 108)-Sequence in Base 3 — Upper bound on s
There is no (49, 109)-sequence in base 3, because
- net from sequence [i] would yield (49, m, 110)-net in base 3 for arbitrarily large m, but
- m-reduction [i] would yield (49, 544, 110)-net in base 3, but
- extracting embedded OOA [i] would yield OOA(3544, 110, S3, 5, 495), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 5048 724587 122425 577275 101757 319130 788548 515367 006696 429671 931108 972073 453425 248775 181485 336665 367346 275384 392035 748694 002292 597541 117361 799478 623513 230660 068926 845938 192778 244867 811520 875056 405598 755215 259235 017197 921517 391945 748112 361990 710921 906430 979595 646221 / 124 > 3544 [i]
- extracting embedded OOA [i] would yield OOA(3544, 110, S3, 5, 495), but
