Yes, one cycle is treated as a product of one factor.
This question is most likely about a problem I am misinterpreting.
Now as far as I can tell this problem is talking about elements of like (12)(34). But . What about elements such as (12)? Or am I being too picky about having to have at least 2 2-cycles?Show that an element has order 2 in iff its cycle decomposition is a product of commuting 2-cycles.
