Gilbertâ€“VarÅ¡amov bound [i]

(133, 133+92, 5246)-Net in Base 4 — Upper bound on s

There is no (133, 225, 5247)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2924 536569 664156 941916 874632 205307 978877 020074 529402 641679 604552 062889 328193 982420 257776 179591 973803 690111 565429 305752 939605 610345 000307 > 4²²⁵ [i]
