(253−118, 253, 2855)-Net in Base 4 — Upper bound on s

There is no (135, 253, 2856)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 212 856393 136765 613938 055752 077133 050991 972613 172593 714305 323593 447597 225141 176597 040808 124238 481240 890827 293361 115084 261956 262454 303816 494504 250662 895712 > 4²⁵³ [i]
