• Steenrod operations
• flag manifolds
• Schubert cells
• Cartan numbers

The classical Schubert cells on a flag manifold G/P give a cell decomposition for G/P whose Kronecker duals (known as Schubert classes) form an additive base for the integral cohomology H*(G/P). We present a formula that expresses Steenrod mod-p operations oil Schubert classes in G/P in terms of Cartan numbers of G.
