    I am not seeing an attachment.

    Is this homework or a question from a textbook??

    The attachment is there now, and no, it's not a homework question. I'm just trying to understand the involution and I wasn't sure where to post it as I haven't been on here in YEARS. Apologies if it is in the incorrect location.

    I'll move it to homework, since it seems to be a textbook-type problem.

    So what did you try to solve the problem? Where are you stuck?

    Pretty much at the beginning, I'm not even entirely sure how to approach the identity.
