(2, 71)-Sequence in Base 25 — Upper bound on s
There is no (2, 72)-sequence in base 25, because
- net from sequence [i] would yield (2, m, 73)-net in base 25 for arbitrarily large m, but
- m-reduction [i] would yield (2, 69, 73)-net in base 25, but
- extracting embedded orthogonal array [i] would yield OA(2569, 73, S25, 67), but
- the linear programming bound shows that M ≥ 24178 564222 846123 668546 399721 917528 895562 151649 914153 732205 158997 548011 257094 913162 291049 957275 390625 / 7242 > 2569 [i]
- extracting embedded orthogonal array [i] would yield OA(2569, 73, S25, 67), but
- m-reduction [i] would yield (2, 69, 73)-net in base 25, but
