COMMENTS
The procedure used to generate the terms of this sequence has similarities with that described in A323286 (Choix de Bruxelles); however here, we don't limit ourselves to divide or multiply by two.
Apparently, all positive integers appear in this sequence.
Multiples of 5 are clustered.

EXAMPLE
The first terms, alongside the substitution that gives a(n+1), are:
n a(n) a(n+1)
-- ---- ------
1 1 (1*2)
2 2 (2*2)
3 4 (4*2)
4 8 (8*2)
5 16 1(6/6)
6 11 1(1*2)
7 12 (12/4)
8 3 (3*2)
9 6 (6*3)
10 18 (18/2)
11 9 (9*3)
12 27 (2/2)7
