Summary: We give several sharp bounds for the Neuman means \(N_{A H}\) and \(N_{H A}\) (\(N_{C A}\) and \(N_{A C}\)) in terms of harmonic mean \(H\) (contraharmonic mean \(C\)) or the geometric convex combination of arithmetic mean \(A\) and harmonic mean \(H\) (contraharmonic mean \(C\) and arithmetic mean \(A\)) and present a new chain of inequalities for certain bivariate means.
