(50−18, 50, 148)-Net over F₄ — Digital

Digital (32, 50, 148)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(50−18, 50, 3050)-Net in Base 4 — Upper bound on s

There is no (32, 50, 3051)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 1 268403 748644 841472 172073 814074 > 4⁵⁰ [i]
