(137, 256, 130)-Net over F4 — Constructive and digital
Digital (137, 256, 130)-net over F4, using
- t-expansion [i] based on digital (105, 256, 130)-net over F4, using
- net from sequence [i] based on digital (105, 129)-sequence over F4, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F4 with g(F) = 105 and N(F) ≥ 130, using
- T7 from the second tower of function fields by GarcÃa and Stichtenoth over F4 [i]
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F4 with g(F) = 105 and N(F) ≥ 130, using
- net from sequence [i] based on digital (105, 129)-sequence over F4, using
(137, 256, 225)-Net over F4 — Digital
Digital (137, 256, 225)-net over F4, using
(137, 256, 2994)-Net in Base 4 — Upper bound on s
There is no (137, 256, 2995)-net in base 4, because
- 1 times m-reduction [i] would yield (137, 255, 2995)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 3357 959205 999448 489134 340865 289445 036895 365656 671278 887526 129661 819804 458144 142987 752237 984451 513263 456237 978562 384958 774929 936891 203620 089385 364352 874688 > 4255 [i]
