I tried to find the maximum by Mathematica:

FindMaximum[{Max[Abs[x + y], Abs[x - y], Abs[2 y]],
Max[Abs[x], Abs[y], Abs[-x + 4 y]] == 1}, {x, y}]

But the output turns out to be

{10.4706, {x -> 8.17647, y -> 2.29412}}

which is incorrect, because Abs[x]>1.

I am wondering how to obtain the correct maximum.

Thanks in advance for any help.
