(87−63, 87, 108)-Net in Base 4 — Upper bound on s
There is no (24, 87, 109)-net in base 4, because
- extracting embedded orthogonal array [i] would yield OA(487, 109, S4, 63), but
- the linear programming bound shows that M ≥ 132 642317 660564 326972 764460 224929 575995 154371 690657 261581 086454 972416 / 4603 991983 561663 > 487 [i]
