 OFFSET 0,1 COMMENTS 16 is included, as 16 = 220 in factorial base and by following the algorithm PermRevLexUnrankAMSD in A055089 we get the composition (2 3)(3 4) (1 2)(2 3) which, although consisting of different transpositions, is equal to the composition (4 2)(3 1) = 3412 produced by algorithm PermUnrank3R at A060117.
