(131, 131+116, 2694)-Net in Base 4 — Upper bound on s

There is no (131, 247, 2695)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 51823 342942 565077 099696 474226 863736 172483 929122 878060 651052 714039 205282 585962 009785 647931 743991 180287 783742 400370 189291 350051 486237 064452 822115 709904 > 4²⁴⁷ [i]
