(250−116, 250, 2898)-Net in Base 4 — Upper bound on s

There is no (134, 250, 2899)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 326356 124318 848570 820772 210884 591416 997249 693731 814763 382402 141179 250334 656331 033479 274587 054761 048798 552277 643323 871900 266291 839923 428673 840966 826472 > 4²⁵⁰ [i]
