I noticed that YAFU was getting stuck, so I ran it by itself, and got the above output. Last fiddled with by Stargate38 on 20200122 at 21:33 Reason: fix link

I can confirm that it doesn't work in the current wip version of yafu. Looks like it fails both the tiny_siqs and smallmpqs routines. Once it fails like this, aliqueit goes into an infinite loop of increasing rho until it succeeds, which is why it took so long. I will look into it.
