(24, 24+44, 201)-Net in Base 4 — Upper bound on s
There is no (24, 68, 202)-net in base 4, because
- the generalized Rao bound for nets shows that 4m ≥ 88828 916417 477753 868929 109704 208142 193680 > 468 [i]
- extracting embedded orthogonal array [i] would yield OA(468, 202, S4, 44), but
- the linear programming bound shows that M ≥ 2027 088631 021403 337954 762092 477564 421959 685162 636703 100335 360507 890568 637631 560712 794323 981191 765389 475840 / 21729 825107 879568 901112 749356 633788 098469 459498 248484 364910 480751 > 468 [i]
