(138, 183, 288657)-Net in Base 4 — Upper bound on s
There is no (138, 183, 288658)-net in base 4, because
- 1 times m-reduction [i] would yield (138, 182, 288658)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 37 577719 249344 503252 571446 547682 302475 210326 738163 770273 289158 722691 006810 197144 537996 779682 198066 677542 916672 > 4182 [i]
