(105−81, 105, 103)-Net in Base 4 — Upper bound on s
There is no (24, 105, 104)-net in base 4, because
- 11 times m-reduction [i] would yield (24, 94, 104)-net in base 4, but
- extracting embedded orthogonal array [i] would yield OA(494, 104, S4, 70), but
- the linear programming bound shows that M ≥ 2905 343984 020254 418179 867462 952821 985360 143012 759289 446224 887808 / 6 994423 > 494 [i]
- extracting embedded orthogonal array [i] would yield OA(494, 104, S4, 70), but
