We give a classification of irreducible representations of generalized Heisenberg groups K n ( F q ) ,   n 5 , which is the pattern group associated to the closed set { ( 1 , i ) ,   ( 2 , j ) ,   ( s , n 1 ) ,   ( t , n ) | 2 i n ,   3 j n ,   3 s < n 1 ,   3 t < n } . In light of the conjectures of Higman, Lehrer and Isaacs for unitriangular groups, this result shows that the number of irreducible characters of K n ( F q ) with a fixed degree is a polynomial in q−1 with non-negative integer coefficients.
