Abstract

Symmetric product orbifolds, i.e. permutation orbifolds of the full symmetric group S_n are considered by applying the general techniques of permutation orbifolds. Generating functions for various quantities, e.g. the torus partition functions and the Klein-bottle amplitudes are presented, as well as a simple expression for the discrete torsion coefficients.
