(53, 138, 2649)-Net in Base 9 — Upper bound on s

There is no (53, 138, 2650)-net in base 9, because

1 times m-reduction [i] would yield (53, 137, 2650)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 54240 032576 403223 404577 186616 756180 185746 931383 563354 947321 237215 727163 484032 225178 618895 683168 199010 920918 607004 107323 164477 464289 > 9¹³⁷ [i]
