چکیده
This paper is dealing with a split extension group of the form $2^{6}{:}(3 \times A_{5}),$ which is the largest maximal subgroup of the Symplectic group $Sp(4,4).$ We refer to this extension by $\overline{G}.$ We firstly determine the conjugacy classes of $\overline{G}$ using the coset analysis technique. The structures of inertia factor groups were determined. We then compute the Fischer matrices of $\overline{G}$ and apply the Clifford-Fischer theory to calculate the ordinary character table of this group. The Fischer matrices of $\overline{G}$ are all integer valued, with sizes ranging from 1 to 4. The full character table of $\overline{G}$ is $26 \times 26$ complex valued matrix and is given at the end of this paper.
