(71−52, 71, 189)-Net in Base 5 — Upper bound on s
There is no (19, 71, 190)-net in base 5, because
- 4 times m-reduction [i] would yield (19, 67, 190)-net in base 5, but
- extracting embedded orthogonal array [i] would yield OA(567, 190, S5, 48), but
- the linear programming bound shows that M ≥ 139 124959 067603 873322 973848 261999 902938 721401 487962 196427 958905 932685 857275 222943 487399 518687 652744 119986 891746 520996 093750 000000 000000 / 1945 405900 784912 155706 111127 555122 141815 117656 438746 607270 389576 779617 403604 841411 250557 > 567 [i]
