Abstract
Recently Li et al Int J Theor Phys 539 2923–2930 2014 presented the concrete representation of density matrix of symmetric quantum states Moreover according to this concrete representation of the density matrix for symmetric quantum states Li et al Int J Theor Phys 539 2923–2930 2014 have established Theorem 41 In this Comment we would like to point out that Theorem 41 given by Li et al Int J Theor Phys 539 2923–2930 2014 is incorrect in general
