(108−77, 108, 136)-Net in Base 4 — Upper bound on s
There is no (31, 108, 137)-net in base 4, because
- extracting embedded orthogonal array [i] would yield OA(4108, 137, S4, 77), but
- the linear programming bound shows that M ≥ 217 390859 331981 319138 219553 931378 186456 570350 958702 486339 017246 642987 932425 092568 449024 / 1975 301566 404582 353457 > 4108 [i]
