(21, 21+66, 138)-Net in Base 5 — Upper bound on s
There is no (21, 87, 139)-net in base 5, because
- extracting embedded orthogonal array [i] would yield OA(587, 139, S5, 66), but
- the linear programming bound shows that M ≥ 314911 252589 678982 955592 780437 601790 628234 495165 860083 330703 714374 904486 804017 335988 909319 527191 308599 883834 418164 951785 001903 772354 125976 562500 / 48451 357963 877144 544304 960539 357735 094650 902841 329614 666232 431720 811360 463254 002671 > 587 [i]
