| Jan 24, 2014 at 13:31 | comment | added | Per Alexandersson | Zeilberger recently put $500 in a donation to the OEIS if a part of Collatz conjecture is solved, see arxiv.org/abs/1401.1532 | |

| May 27, 2011 at 23:06 | comment | added | Gerry Myerson | @Daniel, I'm afraid changing Hungarians hasn't made matters any better. Erdos offered money for his own problems, not for those of other people. Despite what the "informal references" may say, I'd be deeply surprised if Erdos offered anything for settling the Collatz problem. | |

| May 27, 2011 at 14:09 | comment | added | Steven Gubkin | 500 double dollars. I feel like I just walked into a trigun episode. | |
| May 27, 2011 at 9:45 | comment | added | Mark Bell | As the conjecture is stated, False as $\forall N$, $T^N(2^{N+1}) = 2 \neq 1$ but I doubt I'll get \$500 for stating that. | |
| May 27, 2011 at 5:41 | comment | added | Gerry Myerson | The statement is not correct as $N$ must be allowed to depend on $n$. Is there documentation for Halmos' offer? Did the offer expire with the professor? Not that I expect anyone to collect on it any time soon.... | |
