Special distribution methods have been used to make nuclear level-density calculations with full inclusion of two-body forces. The demands on computer time are large, however, and the information obtained in the very lowest energy region is not as extensive as would be desirable. We present calculations of the level density of ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ obtained with an alternative, but closely related, procedure based on the Lanczos algorithm. In addition, we discuss the possibility of accelerating the calculation of the moments for conventional spectral distribution calculations. Very encouraging results for both the Lanczos technique and the revised moment algorithm are obtained; some remaining problems are examined.
