Gilbertâ€“VarÅ¡amov bound [i]

(132, 214, 7435)-Net in Base 4 — Upper bound on s

There is no (132, 214, 7436)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 696 232523 232161 331296 457905 343631 598950 044145 643486 789229 463989 036987 258107 868065 644065 020028 101073 560127 797370 308177 403367 370680 > 4²¹⁴ [i]
