| May 9, 2011 at 0:19 | comment | added | Todd Trimble | Well, I've looked at it a little longer, and I guess I spoke too soon, and I owe you an apology. | |
| May 9, 2011 at 0:18 | comment | added | Luis H Gallardo | Do you really have a solution with odd $n$ ???? should be published. | |

| May 8, 2011 at 23:57 | comment | added | Luis H Gallardo | false: since you take $n$ even, but it may be odd ... | |
| May 8, 2011 at 23:53 | comment | added | Todd Trimble | I really think this is too elementary for this site. The short answer to your question is 'no'. It follows very easily from the binary representation of <a href="en.wikipedia.org/wiki/… perfect numbers</a>. Alternatively, you might try your question over at math.stackexchange.com. | |
