hi!

Could somebody tell me if this is the best way to solve the Katsura 6
problem:

NSolve[{x1 + 2x2 + 2x3 + 2x4 + 2x5 + 2x6 + 2x7 - 1   ,
    2x4 x3 + 2x5 x2 + 2x6 x1 + 2x7 x2 - x6   ,
    x3^2 + 2x4 x2 + 2x5 x1 + 2x6 x2 + 2x7 x3 - x5   ,
    2x3 x2 + 2x4 x1 + 2x5 x2 + 2x6 x3 + 2x7 x4 - x4   ,
    x2^2 + 2x3 x1 + 2 x4 x2 + 2 x5 x3 + 2 x6 x4 + 2 x7 x5 - x3   ,
    2 x2 x1 + 2 x3 x2 + 2 x4 x3 + 2 x5 x4 + 2 x6 x5 + 2 x7 x6 - x2   ,
    x1^2 + 2 x^2 + 2 x3^2 + 2 x4^2 + 2 x5^2 + 2 x6^2 + 2 x7^2 - x1  },
{x1,x2,x3,
x4,x5,x6,x7}]


Thanks,

Raj
