Dear GAP forum, There appears to be a bug with LogFFE:
┌───────┐ GAP 4.10.1 of 23-Feb-2019 │ GAP │ https://www.gap-system.org └───────┘ Architecture: x86_64-apple-darwin18.5.0-default64-kv3 Configuration: gmp 6.1.2 Loading the library and packages ... Packages: AClib 1.3.1, Alnuth 3.1.0, AtlasRep 1.5.1, AutoDoc 2019.02.22, AutPGrp 1.10, Browse 1.8.8, Carat 2.2.3, CRISP 1.4.4, Cryst 4.1.18, CrystCat 1.1.8, CTblLib 1.2.2, FactInt 1.6.2, FGA 1.4.0, GAPDoc 1.6.2, IO 4.5.4, IRREDSOL 1.4, LAGUNA 3.9.2, Polenta 1.3.8, Polycyclic 2.14, PrimGrp 3.3.2, RadiRoot 2.8, ResClasses 4.7.1, SmallGrp 1.3, Sophus 1.24, SpinSym 1.5, TomLib 1.2.7, TransGrp 2.0.4, utils 0.61 Try '??help' for help. See also '?copyright', '?cite' and '?authors' gap> z:=Z(359^2); z gap> LogFFE(z^4,z^2); fail According to the documentation, LogFFE(alpha,beta) should only return "fail" if alpha is not a power of beta. Is 359^2 just too big to ask questions like this?
