(68, 68+49, 431689)-Net in Base 16 — Upper bound on s
There is no (68, 117, 431690)-net in base 16, because
- 1 times m-reduction [i] would yield (68, 116, 431690)-net in base 16, but
- the generalized Rao bound for nets shows that 16m ≥ 47 635262 122879 602841 897083 296801 610632 203150 729707 202185 600316 501019 248816 564121 858238 596572 439265 475964 310047 219722 681848 882464 918917 102276 > 16116 [i]
