(25, 25+66, 110)-Net in Base 4 — Upper bound on s
There is no (25, 91, 111)-net in base 4, because
- extracting embedded orthogonal array [i] would yield OA(491, 111, S4, 66), but
- the linear programming bound shows that M ≥ 55 370157 580736 154116 963294 828751 876036 101137 474368 823948 817345 806336 / 8 191907 762077 > 491 [i]
