Alternatively, one less than the partial sums of A230412 summed from the beginning.

Each n occurs A230405(n) times.

Together with A230412 can be used to compute A230414, A230423 and A230424.

Antti Karttunen, Table of n, a(n) for n = 0..10079

a(0) = 0; and for n>=1, a(n) = A230413(n-1) + A230412(n).

a(A219650(n)) = n for all n.

(Scheme, with memoizing definec-macro from Antti Karttunen's IntSeq-library)

(definec (A230413 n) (if (zero? n) 0 (+ (A230413 (- n 1)) (A230412 n))))

Cf. also A230405, A230412, A230414.

This sequence relates to the factorial base representation (A007623) in a similar way as A046699 relates to the binary system.
