The *primary homotopy operations* are the operations generated by

- the Whitehead products;

and

- the composition operations.

The primary homotopy operations encode via Pi-algebras into an algebraic structure akin to models for a Lawvere theory. (This is discussed more fully in the entry on Pi-algebras.)
