Physicists prefer to use hermitian operators, while mathematicians are not biased towards hermitian operators I thought i would find this with an easy google search What is the fundamental group of the special orthogonal group $so (n)$, $n>2$

I have known the data of $\\pi_m(so(n))$ from this table The generators of so(n) s o (n) are pure imaginary antisymmetric n×n n × n matrices How can this fact be used to show that the dimension of so(n) s o (n) is n(n−1) 2 n (n 1) 2 I know that an antisymmetric matrix has n(n−1) 2 n (n 1) 2 degrees of freedom, but i can't take this idea any further in the demonstration of the proof

Instead, you can save this post to reference later. I have a potentially simple question here, about the tangent space of the lie group so (n), the group of orthogonal $n\times n$ real matrices (i'm sure this can be. U (n) and so (n) are quite important groups in physics
