Best Known (61, s)-Sequences in Base 3
(61, 47)-Sequence over F3 — Constructive and digital
Digital (61, 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
(61, 63)-Sequence over F3 — Digital
Digital (61, 63)-sequence over F3, using
- t-expansion [i] based on digital (49, 63)-sequence over F3, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F3 with g(F) = 49 and N(F) ≥ 64, using
(61, 133)-Sequence in Base 3 — Upper bound on s
There is no (61, 134)-sequence in base 3, because
- net from sequence [i] would yield (61, m, 135)-net in base 3 for arbitrarily large m, but
- m-reduction [i] would yield (61, 534, 135)-net in base 3, but
- extracting embedded OOA [i] would yield OOA(3534, 135, S3, 4, 473), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 49117 362627 542106 424569 766777 759592 841145 602807 758577 568338 354385 898038 247528 906548 185947 296552 815440 128655 712534 888888 911192 807996 160696 178371 455245 509345 055665 936415 304928 006574 745555 215600 945614 367444 563474 858184 450839 992078 414152 895647 500432 015400 282089 / 79 > 3534 [i]
- extracting embedded OOA [i] would yield OOA(3534, 135, S3, 4, 473), but
- m-reduction [i] would yield (61, 534, 135)-net in base 3, but
