Digital (143, 213, 612)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(143, 213, 21356)-Net in Base 4 — Upper bound on s

There is no (143, 213, 21357)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 173 499631 055370 632013 881409 546656 899643 284987 851655 859687 286337 588794 820972 434498 445452 585366 416710 892029 698068 464273 204438 626340 > 4²¹³ [i]
