  We calculate the three-loop anomalous dimension of the non-singlet transverse
operator from N=1 to N=15. Using some guess we have reconstructed a general
form of three-loop anomalous dimension for arbitrary Mellin moment N. Obtained
result is transformed into Bjorken-x space by an inverse Mellin transformation.
The final expressions are presented in both Mellin-N and Bjorken-x space.
