Digital (163, 239, 431)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(163, 239, 7489)-Net in Base 3 — Upper bound on s

There is no (163, 239, 7490)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 1 079388 572528 603163 375698 739166 238432 222577 854681 469303 590705 392326 174134 818968 470619 924810 019376 172227 715843 859197 > 3²³⁹ [i]
