A general method is developed for finding recurrence rules for <em>P<sub>n</sub><sup>k</sup></em> (<em>k</em> fixed); the recurrence rules are given in semiexplicit form for the range 4≤<em>k</em>≤9. A table of <em>P<sub>n</sub><sup>k</sup></em> is included for the range 4≤<em>k</em>≤9, <em>k</em>≤<em>n</em>≤80.
