(102−72, 102, 142)-Net in Base 4 — Upper bound on s
There is no (30, 102, 143)-net in base 4, because
- extracting embedded orthogonal array [i] would yield OA(4102, 143, S4, 72), but
- the linear programming bound shows that M ≥ 57 833620 343797 634544 130580 591815 924041 597402 291621 523905 888652 948345 058555 467190 800870 267187 888128 / 1 840031 759199 955966 201200 096969 140625 > 4102 [i]
