    - a function field by SÃ©mirat [i]

(72, 72+66, 120)-Net over F₄ — Digital

Digital (72, 138, 120)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(72, 72+66, 1418)-Net in Base 4 — Upper bound on s

There is no (72, 138, 1419)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 123017 993613 844570 926949 918910 981990 744554 802729 865918 542361 529319 087687 765447 520712 > 4¹³⁸ [i]
