(123, 123+130, 1787)-Net in Base 4 — Upper bound on s

There is no (123, 253, 1788)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 211 956694 391453 424050 327056 834242 513582 941985 433924 051850 503119 289105 126516 591310 043846 722012 893815 090430 181525 535883 281725 293366 269914 395413 213806 582305 > 4²⁵³ [i]
