Abstract—Let p be a prime greater than seven and A be the mod p Steenrod algebra. In this paper, we prove that the product b_0^2delta_{s+4} is nontrivial, where s is greater than or equal to zero and less than p-4.

Index Terms—Adams spectral sequence cohomology may spectral sequence steenrod algebra.
