A program for generating one-particle and two-particle coefficients of fractional parentage for the single j-orbit with isospin. The program CFPjOrbit written in FORTRAN 90 is aimed at generating the list of one-particle and two-particle coefficients of fractional parentage (CFPs) for the single j-orbit with isospin. The approach is based on a simple enumeration scheme for antisymmetric A-particle states and an efficient method for constructing the eigenvectors of an idempotent matrix as proposed by A. Deveikis, R.K. Kalinauskas and B. R. Barrett [Ann. Phys. 296, No. 2, 287–298 (2002; Zbl 1001.81089)]. The program provides fast calculation of coefficients of fractional parentage for high j-orbits with isospin and produces results that have only small numerical uncertainties. The auxiliary program EnumCFP allows one to perform enumeration of the coefficients.
