I just got an email from Chengyang Bao (cc'ed) pointing out a typo in the Sage reference manual: in the class docstring for sage.modular.arithgroup.congroup_gammaH.GammaH_class, the formula "a, b \in H" should say "a, d \in H". (See https://doc.sagemath.org/html/en/reference/arithgroup/sage/modular/arithgroup/congroup_gammaH.html#sage.modular.arithgroup.congroup_gammaH.GammaH_class ).
It's highly likely that this was my mistake originally, but it's been so long that I can't remember all the version control procedures etc needed to fix it – can some kind person make this single-character fix?
