(139, 255, 3272)-Net in Base 4 — Upper bound on s

There is no (139, 255, 3273)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3405 720120 931843 800051 804342 995525 286545 030079 083466 750501 753641 751003 262061 916754 362354 373175 994906 774468 249296 272614 328866 396334 990124 160193 190040 794080 > 4²⁵⁵ [i]
