Norm is a function that is used to measure size of a vector.
Norms of a vector x given by 
The three common norms are
1) L1 norm when p=1,
2) L2 norm when p=2,
3) Max norm when 
.
.Assume 
Now coming to this question max norm is the one with maximum value (check the field with Maximum) = 1.414
Similarly you can correlate L1 norm and L2 norm.
