For a finite group G, an irreducible character of G is called a ℘-character, if it is a constituent of permutation character (1_M)^G for some maximal subgroup M of G. n this article, we determine the ℘-characters of group PSL(2,q), and we check which of the permutation characters (1_M)^PSL(2,q) are multiplicity-free.
