| Nov 27, 2016 at 21:51 | comment | added | j0equ1nn | @DavidWhite The math involved in answering this may not be "research level," but I thought some users of this site would share my curiosity in answering it since it pertains to our community (and some did). I don't think that personally finding a question frivolous is sufficient for rejecting it as off-topic, but I do think I should have marked it as a "soft question," which I've now done. | |

| Nov 27, 2016 at 1:17 | comment | added | j0equ1nn | @PatDevlin Yeah, that's how I felt at first too. Like, saying that the graph is non-planar is basically just saying there has been an instance of multiple advisors in a way that caused it, but this isn't how the analysis is presented. I'd like to see it put that way. | |

boldfaced main question

| Nov 27, 2016 at 1:13 | comment | added | Pat Devlin | The thing is probably very close to a forest, as very few people have more than one advisor. | |
| Nov 27, 2016 at 1:10 | comment | added | j0equ1nn | @PatDevlin I wonder if that data is available, though the data I suggest attaining is more specific to the nature of this graph. | |
