The general name for the stable cohomology operations (cf. Cohomology operation) created by N.E. Steenrod for every prime number . The first example is contained in [1]. For this is the Steenrod square , for the Steenrod reduced power . The operations multiplicatively generate the Steenrod algebra modulo 2, while the operations together with the Bockstein homomorphism generate the Steenrod algebra modulo .
