(244−130, 244, 1466)-Net in Base 4 — Upper bound on s

There is no (114, 244, 1467)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 823 325029 300779 223952 343958 387309 486783 674699 934832 903185 301389 859110 969900 602770 085108 072411 620629 407992 126252 646502 581977 613569 698853 476685 684380 > 4²⁴⁴ [i]
