      - the Hermitian function field over F₁₆ [i]

(99−18, 99, 681)-Net over F₂ — Digital

Digital (81, 99, 681)-net over F₂, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OOA(2⁹⁹, 681, F₂, 3, 18) (dual of [(681, 3), 1944, 19]-NRT-code), using

(99−18, 99, 8480)-Net in Base 2 — Upper bound on s

There is no (81, 99, 8481)-net in base 2, because

the generalized Rao bound for nets shows that 2^mÂ â‰¥ 634224 769080 046593 551464 007768 > 2⁹⁹ [i]
