(140, 140+120, 3092)-Net in Base 4 — Upper bound on s

There is no (140, 260, 3093)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 476696 603104 399893 823521 598878 274211 031133 597188 340606 040907 481770 230129 854198 560941 950756 472120 668487 608856 205337 079871 827139 851507 305842 790002 650348 433280 > 4²⁶⁰ [i]
