(81−52, 81, 102)-Net in Base 3 — Upper bound on s
There is no (29, 81, 103)-net in base 3, because
- extracting embedded orthogonal array [i] would yield OA(381, 103, S3, 52), but
- the linear programming bound shows that M ≥ 1648 634351 113215 149715 784496 019469 628928 501125 836083 / 3 036794 593547 > 381 [i]
