| Feb 18, 2014 at 15:04 | comment | added | JTP - Apologise to Monica | I'm no longer voting via my iPad. I'm sorry I am the DV, by accident of course, and unlike typos, I can't reverse, unless answer is edited. Not the first time this has happened. | |
| Feb 18, 2014 at 15:01 | comment | added | Ross Millikan | @AviD: the puzzle can be solved without knowing that at least one tells the truth, and the comments to another answer suggest a way to reword it so you are not given that information. The way it is worded does tell you that. I think one is free to use that information. | |
| Feb 18, 2014 at 14:48 | comment | added | LarsH | @AviD: by definition, a hint is a statement giving information that could already be inferred from information already given. So, how can any hint not be "irrelevant" in this way? In other words, I don't see how nbubis' statement is less "relevant", or less "additional", than Ross's. | |
| Feb 18, 2014 at 14:28 | comment | added | LarsH | @AviD: why is nbubis' statement irrelevant? Just because the same information can be inferred by a different path? | |

| Feb 16, 2014 at 15:35 | comment | added | Martin Smith | Or to restate the point another way 28 legs would require the blue octopus to be both telling the truth and have 7 legs and we are told that 7 legged Octopuses always lie. | |
| Feb 16, 2014 at 12:12 | comment | added | AviD | @nbubis that is irrelevant, since if all 4 were lying, there would be exactly 28 legs, which is what the blue one said, which means the blue one was not lying, which means only 3 were lying... | |
| Feb 15, 2014 at 23:03 | comment | added | Nathaniel Bubis | And additionally, exactly three lie, since the question asks about the truth teller. | |

| Feb 15, 2014 at 16:17 | comment | added | Hawk | Awesome hint...(+1)...I really was confused about this one | |
