(253−114, 253, 3414)-Net in Base 4 — Upper bound on s

There is no (139, 253, 3415)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 212 852400 143358 269690 127377 169701 062018 842936 065301 224712 882172 294045 996529 011512 968360 537675 583598 685993 053922 864132 494974 597822 093878 307272 796974 896720 > 4²⁵³ [i]
