%F a(n) = A051903(A275725(n)).

%e For n=27, which in factorial base (A007623) is "1011" and encodes (in A060118-order) permutation "23154" with one 3-cycle and one 2-cycle, the longest cycle has three elements, thus a(27) = 3.

%o (Scheme) (define (A275803 n) (A051903 (A275725 n)))

%Y Cf. A007623, A060117, A060118.

%Y Cf. A051903, A275725.

%Y Cf. A261220 (gives the positions of 1 and 2's).

%Y Differs from A060131 for the first time at n=27, where a(27) = 3, while A060131(27) = 6.
