  • An OD-characterizable class of simple groups 
    Akbari, M.; Chen, X.Y.; Moghaddamfar, A.R. (Algebra and Discrete Mathematics, 2020)
    It is proved that nonabelian finite simple groups S with max π(S) = 37 are uniquely determined by their order and degree pattern in the class of all finite groups.
  • Some properties of various graphs associated with finite groups 
    Chen, X.Y.; Moghaddamfar, A.R.; Zohourattar, M. (Algebra and Discrete Mathematics, 2021)
    In this paper we investigate some properties of the power graph and commuting graph associated with a finite group, using their tree-numbers. Among other things, it is shown that the simple group L₂(7) can be characterized ...
