(28, 68, 153)-Net in Base 3 — Upper bound on s
There is no (28, 68, 154)-net in base 3, because
- extracting embedded orthogonal array [i] would yield OA(368, 154, S3, 40), but
- the linear programming bound shows that M ≥ 1543 058592 964362 627616 920522 828367 173876 303246 223002 800564 908980 622587 014726 821210 979933 875704 730374 337724 405572 586571 638574 502256 542100 430421 331132 939258 230113 015935 536697 467246 600185 034473 231953 255137 438105 864201 753265 543937 797738 079087 583095 / 5 223863 926286 388649 771330 591111 717512 853140 916572 381721 122477 739536 180288 144562 059465 186434 644433 474885 418173 813040 846526 036560 913385 399148 362432 124880 619677 394872 674126 851680 403717 510145 188107 930768 075751 656943 > 368 [i]
