(18, 18+117, 143)-Net in Base 8 — Upper bound on s
There is no (18, 135, 144)-net in base 8, because
- 7 times m-reduction [i] would yield (18, 128, 144)-net in base 8, but
- extracting embedded orthogonal array [i] would yield OA(8128, 144, S8, 110), but
- the linear programming bound shows that M ≥ 6109 893966 434273 613815 828543 318095 703793 603744 881950 919851 825987 742070 359262 466307 770153 217353 472069 496822 008994 926770 763501 404160 / 124 535855 141787 > 8128 [i]
- extracting embedded orthogonal array [i] would yield OA(8128, 144, S8, 110), but
