I was trying to find the nuber of permutation on n objects with only odd length cycles (so the order is odd).
i found it by exponential generating function (catalan numbers are part of it - see the file) but i wonder if anyone knows about a combinatorical way to find this number? i upload the number i found.
Hi, i am so good with combinatorial problems
I am online now and i have a doubt about your question (i checked it )
I wait your PM to discuss about it
Thanks
