Centrosymmetric matrix

Imagine you have a puzzle with a mirror in the middle. If you place a piece on one side of the mirror, you automatically have to place the same piece on the other side, in the same exact spot. This is what a centrosymmetric matrix is like - it looks the same on both sides of a mirror, and the mirrored part is an exact copy of the original. In math, we call this "reflection symmetry." It's like the puzzle piece has a twin on the other side of the mirror who always matches it perfectly!
