How to swap rows in square a matrix algebraically

Splet14. apr. 2024 · For example, to change (1 2 3) to (3 1 2), you might swap 2 and 3 to get (1 3 2), then swap 1 and 3 to get (3 1 2). This is an even number of swaps, so it is an even permutation, and is labeled with \(+1\). To get from there to (3 2 1) would require a third swap, making it odd. Splet08. nov. 2013 · 1 Here are some ideas that may help the thought process, presented as a HINT.
