Digital (121, 181, 298)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(121, 181, 4524)-Net in Base 3 — Upper bound on s

There is no (121, 181, 4525)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 229 209900 812114 161396 332307 357490 210135 378929 648845 511295 113792 407048 994756 590939 429553 > 3¹⁸¹ [i]
