(26, ∞, 91)-Net in Base 4 — Upper bound on s
There is no (26, m, 92)-net in base 4 for arbitrarily large m, because
- m-reduction [i] would yield (26, 272, 92)-net in base 4, but
- extracting embedded OOA [i] would yield OOA(4272, 92, S4, 3, 246), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 921 377545 122446 619199 598286 374089 084696 513969 828232 526459 034741 270904 336521 520715 841339 532514 076847 544303 802497 745079 321233 052888 165232 576308 943909 041185 557531 590656 / 13 > 4272 [i]
- extracting embedded OOA [i] would yield OOA(4272, 92, S4, 3, 246), but
