of a tone row, input f in numeric form and the values of the exponents i,j,k,m,n,r,s. According to the definition of this group action the sequence of Sm Rn Fr acting on the domain of f must be reversed and the exponent m must be replaced by -m. Since r,n∈ {0,1} the minus can be omitted in front of r or n.
(TiIjQk ,Sm Rn Fr) o Ps * f= Ti o Ij o Qk o Ps o f o Fr o Rn o S-m..
