(109−78, 109, 134)-Net in Base 4 — Upper bound on s
There is no (31, 109, 135)-net in base 4, because
- extracting embedded orthogonal array [i] would yield OA(4109, 135, S4, 78), but
- the linear programming bound shows that M ≥ 1 381415 346084 105880 317215 393836 473441 211153 164709 215619 710745 577423 733411 192078 598144 / 3 210734 020015 964827 > 4109 [i]
