<s>[INST] I have a_ij matrix and I want to find the maximum number of horizontal, vertical, and anti-diagonal lines that can pass through a grid once. I am only looking for integer values. The details are as following:

each element a_ij represents the number of these lines that can pass through cell i*x+j; 

Values in the cell are not to be modified.

When i=1, j=1 means top left corner of grid 

When i=n, j=n means the bottom right corner of grid

I am trying to find m maximum value i and j satisfying the condition of a_ij = m

ुनel_needed is the number of lines that will pass through the grid.

I have a_ij = (n- i) * 4
where n = 8 

There is a symmetric solution for m. 

Here is my code is python:
