(69−45, 69, 194)-Net in Base 4 — Upper bound on s
There is no (24, 69, 195)-net in base 4, because
- extracting embedded orthogonal array [i] would yield OA(469, 195, S4, 45), but
- the linear programming bound shows that M ≥ 82 828010 425088 398135 365726 677314 464149 340113 774380 345347 664035 522400 039552 947596 743692 557981 180235 874304 000000 / 227 578582 237535 291818 752893 814619 068871 044126 923591 235904 712727 792773 > 469 [i]
