Abstract: Using known all-loop results from the BFKL and generalized doublelogarithmic
equations and large spin limit we have computed the ve-loop anomalous dimension
of twist-2 operators without consideration of any wrapping eects. One part of
the anomalous dimension was calculated in a usual way with the help of Asymptotic Bethe
Ansatz. The rest part, related with the wrapping eects, was reconstructed from known
constraints with the help of methods from the numbers theory.
