Gilbertâ€“VarÅ¡amov bound [i]

(133, 213, 8412)-Net in Base 4 — Upper bound on s

There is no (133, 213, 8413)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 173 302552 286490 805060 880107 966042 262773 305079 945340 004100 043687 354584 125058 424867 708897 781008 849510 154596 631573 676137 790634 233870 > 4²¹³ [i]
