1347 N-level cube

Description

The so-called "N-level cube" is a number filling game ~ N ^ 2 numbers are repeatedly filled in a square matrix consisting of n rows and n columns, N ^ 2 squares, the sum of numbers in each row, column, and diagonal line in the square matrix is equal to the same number, and N is an odd number.

(Follow the 89 pages of the teaching material strictly.AlgorithmOperation. If the write is not performed as required, the non-AC status will occur and the consequences will be borne by you)

Input

The first behavior t indicates that T groups of data exist.

Each of the following lines contains an integer n (n <= 10)

Output

Corresponding to the Cube filled in for each N output, each number has a space, each n numbers a row

 

 

 

 

Find the rule and print it cyclically.
