In that case, I would like to draw your attention to an important property: no matter how you swap rows and columns, you preserve the numbers in a particular (labeled) row or column. Let me give you an example.

Consider the matrix

The first column contains the numbers 15, 4, 8, 3. If I swap a few rows and columns, I might receive

Observe that I still have a column that contains 15, 4, 8, 3 - they are just permuted.

Can you see how to use this property to show that your matrices cannot be transformed into one another?
