This group is the second largest maximal subgroup of thesporadic Thompson simple group $mathrm{Th}.$ In this paper wecalculate the Fischer matrices of Dempwolff group $overline{G} =2^{5}{^{cdot}}GL(5,2).$ The theory of projective characters isinvolved and we have computed the Schur multiplier together with aprojective character table of an inertia factor group. The fullcharacter table of $overline{G}$ is then can be calculated easily. %K Group extensions %K Dempwolff group %K character table %K Clifford theory %K inertia groups %K Fischer matrices %K Schur multiplier %K projective characters %K covering group %U http://www.theoryofgroups.ir/?_action=showPDF&article=1590&_ob=e7bcdc949b15b34554b46d8c59cfc1ce&fileName=full_text.pdf
