 OFFSET 0,2 COMMENTS Function for a partition P with maximum part size k, the number of endofunctions with indegree partition P + [m] for any m > k. Larger values of m just add additional points with empty preimage that map to the element with indegree m. Partitions are in Mathematica order. LINKS EXAMPLE The fifth partition in Mathematica order is [2,1]. The number of endofunctions with indegree partitions [3,2,1] is 19 (likewise for [4,2,1], [5,2,1], etc.), so a(5) = 19. The triangle starts: 1 3 4 8 4 19 18 4 20 14 64 38 CROSSREFS Sequence in context: A021291 A179104 A198125 * A086850 A245598 A340533 Adjacent sequences:  A127119 A127120 A127121 * A127123 A127124 A127125 KEYWORD more,nonn,tabf AUTHOR Franklin T.
