(64, 206, 451)-Net in Base 4 — Upper bound on s

There is no (64, 206, 452)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 11915 362977 449536 710577 257269 392172 601746 829239 617015 598886 980523 409579 409365 089078 550699 416413 667308 051097 357433 601819 820640 > 4²⁰⁶ [i]
