Information on Result #1869846
There is no (18, 18+k, 87)-net in base 5 for arbitrarily large k, because logical equivalence would yield (18, m, 87)-net in base 5 for arbitrarily large m, but
- m-reduction [i] would yield (18, 257, 87)-net in base 5, but
- extracting embedded OOA [i] would yield OOA(5257, 87, S5, 3, 239), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 1 295425 283264 166693 807952 779420 059935 667400 054665 442207 753555 520525 288770 474364 058695 726125 520843 233984 082094 091922 449539 549264 842024 792004 047950 566558 711216 202937 066555 023193 359375 / 2 > 5257 [i]
- extracting embedded OOA [i] would yield OOA(5257, 87, S5, 3, 239), but
