Monks has recently shown that the element Pb has nilpotence height 2[s/t] + 2 in the mod 2 Steenrod algebra. Here the method and result are generalized to show that for an odd prime p the element Pb has nilpotence height p[s/t] + p in the mod p Steenrod algebra.en10.1090/S0002-9947-99-01906-6info:eu-repo/semantics/openAccessArticle3512547558WOS:000078402200006Q1
