Larger values of m just add additional points with empty preimage that map to the element with indegree m. Partitions are in Mathematica order. %e A127122 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. %e A127122 The triangle starts: %e A127122 1 %e A127122 3 %e A127122 4 8 %e A127122 4 19 18 %e A127122 4 20 14 64 38 %Y A127122 Cf.
