(85, 251, 633)-Net in Base 4 — Upper bound on s

There is no (85, 251, 634)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 14 441655 486039 072652 533104 372530 373062 259438 849783 068051 644403 244352 633546 613249 331117 153459 489697 954397 096117 471977 349228 010455 412582 379220 214052 598036 > 4²⁵¹ [i]
