(25, 25+47, 205)-Net in Base 4 — Upper bound on s
There is no (25, 72, 206)-net in base 4, because
- 1 times m-reduction [i] would yield (25, 71, 206)-net in base 4, but
- extracting embedded orthogonal array [i] would yield OA(471, 206, S4, 46), but
- the linear programming bound shows that M ≥ 12190 666552 860549 875030 280693 949215 033597 089167 787297 540990 306499 998443 349891 008938 804128 810849 723006 100908 802048 / 2095 122091 727468 263392 248874 603589 540011 988045 238608 933987 894642 253863 > 471 [i]
- extracting embedded orthogonal array [i] would yield OA(471, 206, S4, 46), but
