Group theory (especially finite group theory).

subgroup : general subgroup theories, quotient group using quot

finsubg : finite subgroups (finset and fintype), Lagrange theorem, finite cosets and lcoset_type, normalizer for finite groups, coset product and quotient group based on lcoset_type, semidirect product

hom : homomorphism and isomorphism, kernel, first isomorphism theorem

perm : permutation group

cyclic : cyclic subgroup, finite generator, order of generator, sequence and rotation

action : fixed point, action, stabilizer, orbit stabilizer theorem, orbit partition, Cayley theorem, action on lcoset, cardinality of permutation group

pgroup : subgroup with order of prime power, Cauchy theorem, first Sylow theorem
