(130, 56)-Sequence over F2 — Constructive and digital
Digital (130, 56)-sequence over F2, using
- t-expansion [i] based on digital (110, 56)-sequence over F2, using
- Niederreiter–Xing sequence construction III based on the algebraic function field F/F2 with g(F) = 69, N(F) = 48, 1 place with degree 2, and 8 places with degree 6 [i] based on function field F/F2 with g(F) = 69 and N(F) ≥ 48, using an explicitly constructive algebraic function field [i]
(130, 80)-Sequence over F2 — Digital
Digital (130, 80)-sequence over F2, using
- t-expansion [i] based on digital (126, 80)-sequence over F2, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F2 with g(F) = 126 and N(F) ≥ 81, using
(130, 139)-Sequence in Base 2 — Upper bound on s
There is no (130, 140)-sequence in base 2, because
- net from sequence [i] would yield (130, m, 141)-net in base 2 for arbitrarily large m, but
- m-reduction [i] would yield (130, 977, 141)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2977, 141, S2, 7, 847), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 73 446923 390877 689068 954515 839755 659231 282206 384024 837527 293738 521689 397620 777877 620886 453130 128993 800087 802043 866283 824978 185717 972884 246715 201522 176881 796267 776208 764599 952895 845388 149152 557928 321643 528199 216402 954573 824748 448030 311109 873878 888024 996262 049373 027822 332438 792624 476659 565346 160640 / 53 > 2977 [i]
