Constructing the ordinary character tables of some Atlas groups using   character theoretic methods
  We compute the character tables of the following groups with character theoretic methods, using known information about the conjugacy classes and about the character tables of some subgroups and factor groups: $Th$, $J_4$, $2.{}^2E_6(2)$, $2.{}^2E_6(2).2$, and $2.B$.
