(19, 19+∞, 27)-Net over F7 — Constructive and digital
Digital (19, m, 27)-net over F7 for arbitrarily large m, using
- net from sequence [i] based on digital (19, 26)-sequence over F7, using
(19, 19+∞, 54)-Net over F7 — Digital
Digital (19, m, 54)-net over F7 for arbitrarily large m, using
- net from sequence [i] based on digital (19, 53)-sequence over F7, using

(19, 19+∞, 133)-Net in Base 7 — Upper bound on s
There is no (19, m, 134)-net in base 7 for arbitrarily large m, because
- m-reduction [i] would yield (19, 265, 134)-net in base 7, but
- extracting embedded OOA [i] would yield OOA(7265, 134, S7, 2, 246), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 26887 294207 970268 759601 657658 889776 095045 375361 275265 172861 260229 563982 961931 156601 013406 360427 771092 477311 182639 767908 335162 075873 790268 224023 707340 408699 369167 136353 848535 631815 185217 453099 342933 554750 719155 927758 584420 150907 / 247 > 7265 [i]
