  It is shown that the representation transformations of multiquark wave
functions between different coupling schemes are just the Racah coefficients of
the permutation group. The transformation coefficients between the flavor-spin
(FS) and the color-spin (CS) schemes are obtained. As an example, the expansion
of the physical bases in terms of symmetry bases in the CS scheme are given for
the interesting cases $YIJ = 201, 210, 000$.
