I will talk on a new class of algebras called "Lie antialgebras". These graded commutative algebras are closely related to Lie superalgebras. I will give a number of examples of Lie antialgebras and explain their main properties. A part of the talk will treat the classical algebra of quaternions viewed as a graded commutative algebra.
