Abstract
The aim of this work is to study the universal Steenrod algebra Q p for odd primes p. An invariant-theoretic description of Q p is given and two families of algebras related to Q p are presented. They include the algebra Λ opp , the Steenrod algebra 𝒜 p and the Steenrod algebra for simplicial restricted Lie algebras A L as particular cases. The diagonal cohomology D*(Q p ) is computed.
