Gilbertâ€“VarÅ¡amov bound [i]

(183−68, 183, 7821)-Net in Base 4 — Upper bound on s

There is no (115, 183, 7822)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 150 363260 082598 574247 241554 931051 885542 930778 583865 827997 095741 926159 399742 101106 829165 457649 618993 700833 104360 > 4¹⁸³ [i]
