(105, 251, 1037)-Net in Base 4 — Upper bound on s

There is no (105, 251, 1038)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13 109464 638603 241010 893604 611628 315427 256393 418298 755042 301402 277908 123149 067530 500012 253656 823395 816588 898919 701540 159546 814146 673812 729105 461750 183600 > 4²⁵¹ [i]
