Digital (125, 205, 324)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(205−80, 205, 6367)-Net in Base 4 — Upper bound on s

There is no (125, 205, 6368)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2645 398635 004685 184916 741998 180086 929889 239809 949574 300045 868183 188605 026845 498114 562824 502130 705389 243336 671237 010787 215382 > 4²⁰⁵ [i]
