In the talk will consider abnormal trajectories in the sub-Riemannian problem with grouth vector (2,3,5,8) in nondegenerate case. We study abnormal trajectories which are not one-parametric subgroups of the state space tangent to the distribution Δ. We obtain parametric equations of abnormal controls, describe the structure of the cooresponding abnormal trajectories which lie in annihilator of square of Δ. We characterize strictly and nonstrictly abnormal trajectories. The main method of solving this problem is the Pontryagin maximum principle.
