Digital (124, 206, 305)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(206−82, 206, 5665)-Net in Base 4 — Upper bound on s

There is no (124, 206, 5666)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 10644 687251 286319 714946 757849 542315 415188 468949 028589 871548 597466 200887 124637 059854 137926 678669 741524 691990 284680 425466 774976 > 4²⁰⁶ [i]
