FORMULA

Can be also obtained by mapping with an appropriate permutation from the products of parts of each partition computed for other enumerations similar to A125106:

a(n) = A227184(A006068(n)).

a(n) = A003963(A005940(n+1)).

a(n) = A243504(A163511(n)).

PROG

(Scheme)

(define (A243499 n) (let loop ((n n) (i 1) (p 1)) (cond ((zero? n) p) ((even? n) (loop (/ n 2) (+ i 1) p)) (else (loop (/ (- n 1) 2) i (* p i))))))
