HOMFLY for twist knots and exclusive Racah matrices in representation [333]

Next step is reported in the program of Racah matrices extraction from the differential expansion of HOMFLY polynomials for twist knots: from the double-column rectangular representations R=[rr] to a triple-column and triple-hook R=[333]. The main new phenomenon is the deviation of the particular coefficient f[332][21] from the corresponding skew dimension, what opens a way to further generalizations.
