(183, 183+41, 867298)-Net in Base 3 — Upper bound on s
There is no (183, 224, 867299)-net in base 3, because
- 1 times m-reduction [i] would yield (183, 223, 867299)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 25006 188195 632888 943442 866763 715610 809617 672595 579413 597895 540914 537016 391127 011893 277918 272398 459179 629241 > 3223 [i]
