%N Number of different 5th-power (quintic) mappings of a finite set of n elements into itself.
%C The same as A102687 (square composition), A163859 (cubic composition), A163860 (4th-power composition), here a(n) is the number of different mappings g that admit at least one mapping f as the 5th-order root (g=fofofofof) in terms of the composition.
%Y Cf. A102687, A163859, A163860.
