Gilbertâ€“VarÅ¡amov bound [i]

(158, 158+94, 10313)-Net in Base 4 — Upper bound on s

There is no (158, 252, 10314)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 52 405572 702054 505756 750905 858879 597971 313798 891616 520759 924714 704946 179427 579513 869995 607042 049005 421548 284742 567741 992501 759857 603955 114981 015778 554400 > 4²⁵² [i]
