Abstract: A 20-year-old conjecture about the mod 2 Steenrod algebra , namely that the element has nilpotence height , is proved. The proof uses formulae of D. M. Davis and J. H. Silverman to obtain commutation relations involving `atomic' and the canonical antiautomorphism of , together with a `stripping' technique for obtaining new relations in from old. This construction goes back to Kristensen [Math. Scand. 16 (1965), 97--115].
