Abstract
In this paper, we determine some nontrivial secondary Adams differentials on the fourth line \({\rm{Ext}}_{\cal A}^{4, *}({\mathbb{Z}}/p,{\mathbb{Z}}/p)\) of the classical Adams spectral sequence. Specially, among these differentials, two of them are obtained via the matrix Massey products.
