The objective of this paper is to obtain an upper bound to the second Hankel determinant vertical bar a(2)a(4) - a(3)(2)vertical bar for the function f, belonging to the class of Gamma-starlike functions, using Toeplitz determinants. The result presented here include two known results as their special cases.
