The authors present the power series expansions of the function R (a)− B (a) at a= 0 and at a= 1/2, show the monotonicity and convexity properties of certain familiar combinations defined in terms of polynomials and the difference between the so-called Ramanujan constant R (a) and the beta function B (a)≡ B (a, 1− a), and obtain asymptotically sharp lower and upper bounds for R (a) in terms of B (a) and polynomials. In addition, some properties of the Riemann zeta function ζ (n), n∈ N, and its related sums are derived.
