(26, 26+61, 138)-Net in Base 4 — Upper bound on s
There is no (26, 87, 139)-net in base 4, because
- extracting embedded orthogonal array [i] would yield OA(487, 139, S4, 61), but
- the linear programming bound shows that M ≥ 58021 033010 082048 346589 539539 650556 829549 013896 982516 222865 579789 809390 182651 079156 091854 407840 439381 387477 254144 / 2 173978 495196 124675 726832 016972 933278 429456 491977 566905 040725 > 487 [i]
