It is not hardcoded in mmj2, although it might be in the blacklist (which gets out of date relatively quickly anyway and knows how to handle it). Regarding the naming, I think it is a bit odd that a theorem called a1ii does not use ax-1. Then again, idi doesn't use id either. On Tue, Nov 10,

Hi all, I would like to relabel ~dummylink to ~a1ii, since it is the inference associated with ~a1i (and "dummylink" is not the prettiest word). As Norm told me, this might have a few consequences, so I would need some agreements before carrying on with the change: * I would propagate this
