The determinant of any odd anti-symmetric matrix is 0, and the determinant of any even anti-symmetric matrix is a square (known as the Pfaffian). The first part is completely elementary and follows from applying the determinant to the identity $A=-A^T$, while the second part is due to Cayley and has several proofs. | |
