Amplitudes of the dominant finite-size corrections to part of the eigenspectrum are obtained analytically. A comparison with Cardy's predictions from the theory of conformal invariance leads to the exact results for the conformal anomaly and scaling dimensions.3enConformal anomaly and scaling dimensions of the O(n) model from an exact solution on the honeycomb lattice198810.1103/PhysRevLett.61.1380001304726
