Digital (144, 254, 280)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(144, 144+110, 4244)-Net in Base 4 — Upper bound on s

There is no (144, 254, 4245)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 839 423338 965771 640239 687756 694109 182120 008021 470421 251416 460148 933971 358636 536482 583714 178768 797634 980788 027677 914994 719079 733300 439920 835069 812004 449408 > 4²⁵⁴ [i]
