| Summary:
After analyzing the 4×4 determinant of a matrix, a shortcut was obtained to
find such a determinant. Similarly to the Sarrus method for 2×2 or 3×3
determinants, the method consists of laying 19 columns of size 4 each and
adding and subtracting some diagonal multiplications. There is a symmetry in
the arrangement of these columns. A very symmetric pattern emerged for the 5×5
determinant which was also found. A cyclic pattern was observed for the
diagonals of larger determinants when applying this method.
