Special objects

  • terminal object: trivial group
  • initial object: trivial group
  • products: [finite case] direct products with pointwise operations
  • coproducts: [finite case] free products

Special morphisms

  • isomorphisms: bijective homomorphisms
  • monomorphisms: injective homomorphisms
  • epimorphisms: surjective homomorphisms
  • regular monomorphisms: same as monomorphisms
  • regular epimorphisms: surjective homomorphisms whose kernel is the normal closure of finitely many elements
