(165−105, 165, 253)-Net over F3 — Upper bound on s (digital)
There is no digital (60, 165, 254)-net over F3, because
- extracting embedded orthogonal array [i] would yield linear OA(3165, 254, F3, 105) (dual of [254, 89, 106]-code), but
- residual code [i] would yield OA(360, 148, S3, 35), but
- the linear programming bound shows that M ≥ 32736 674181 247111 523198 040277 032547 478736 312432 761773 182980 156745 054076 913794 735387 713391 860471 994046 617776 080101 939907 837612 473720 955089 815789 352300 892160 / 691974 074846 423845 929231 601971 384016 174717 370524 100041 408052 710499 582060 732735 640083 715550 709077 494269 293566 444659 318525 072647 > 360 [i]
- residual code [i] would yield OA(360, 148, S3, 35), but
(165−105, 165, 274)-Net in Base 3 — Upper bound on s
There is no (60, 165, 275)-net in base 3, because
- 1 times m-reduction [i] would yield (60, 164, 275)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 1 778118 269114 122717 059046 294342 972006 540253 047212 712053 458189 964998 253099 815289 > 3164 [i]
