Digital (145, 213, 385)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(145, 145+68, 6565)-Net in Base 3 — Upper bound on s

There is no (145, 213, 6566)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 424689 838510 520432 813982 351904 656336 990929 616499 709143 426273 745287 037058 422530 991469 334273 951254 351213 > 3²¹³ [i]
