I am a 19-year-old amateur mathematician, who mostly edits articles about prime numbers. A freshman in college in Fall 2007, I am not yet fully-developed as a mathematician. I am a Mathematics and Computer Science double major, who is only getting better with each passing day.
Sorry for the intrusion, but editing your user information was the only way to get your attention. I can prove that C5 is indeed prime! You can view my answer on my website... www.oddperfectnumbers.com. I have two actual calculations that support my answer. You can just delete this message, after you've seen my argument. Thanks, Bill. leavemsg1@yahoo.com 24.1.224.139 (talk) 16:13, 12 September 2012 (UTC)
