(20, 20+61, 1288)-Net in Base 16 — Upper bound on s
There is no (20, 81, 1289)-net in base 16, because
- 1 times m-reduction [i] would yield (20, 80, 1289)-net in base 16, but
- the generalized Rao bound for nets shows that 16m ≥ 2 147153 147676 939105 854576 035642 019124 526529 671475 685044 098317 755223 314987 322359 823553 235785 538176 > 1680 [i]
