Digital (140, 234, 331)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(140, 140+94, 6049)-Net in Base 4 — Upper bound on s

There is no (140, 234, 6050)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 766 056211 288211 960430 028106 699704 997999 545837 291229 386923 038159 690668 296012 027244 224924 756710 261753 995160 753839 868054 799955 340889 369689 079232 > 4²³⁴ [i]
