About isomorphisms[edit]
In § 4, Homomorphisms and isomorphisms, why's isomorphisms being mentioned in the title, but not in the section itself? Are all homomorphisms also isomorphisms? That should be written then.

 I've added the definition of isomorphism; not every homomorphism is an isomorphism. Andrewbt (talk) 05:45, 31 December 2017 (UTC)
Antiabsorption[edit]
Another useful identity (theorem, not axiom) is:
 a ∨ (¬a ∧ b) = a ∨ b
 a ∧ (¬a ∨ b) = a ∧ b
Does this have a standard name? It follows immediately from distributivity, of course. Should it be mentioned in the article? Macrakis (talk) 20:09, 26 March 2021 (UTC)
