  • In this paper, we will demonstrate how the character table of a sub-maximal subgroup $2^6{:}(2^5{:}S_6)$ of the sporadic simple group $Fi_{22}$ can be used to obtain the conjugacy classes and character table of a non-split extension of the form $2^6{{}^{\cdot}}(2^5{:}S_6)$, which sits maximal in the unique non-split extension $2^6{{}^{\cdot}}Sp_6(2)$.
