Gilbertâ€“VarÅ¡amov bound [i]

(149, 219, 6689)-Net in Base 3 — Upper bound on s

There is no (149, 219, 6690)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 308 852031 592064 195669 248704 872964 231553 647969 646339 647626 609596 893309 473356 269290 053609 649429 519009 137809 > 3²¹⁹ [i]
