Let G be a finite group and χ∈\irr(G). The codegree of χ is defined as \cod(χ)=χ(1)∣G:ker(χ)∣ and \cod(G)={\cod(χ) ∣ χ∈\irr(G)} is called the set of codegrees of G. In this paper, we show that the set of codegrees of \Sy4(4),\U4(2), \Sy4(q) (q≥4), \U4(3), 2\F4(2)′, \J3, \G2(3), \A9, \J2, \PSL(4,3), \McL, \Sy4(5), \G2(4), \HS, \ON and \M24 determines the group up to isomorphism.
