COMMENTS
| See various attractors in A098191-A098195.
For n below 10^6, cycle-lengths are one of {1,2,5,6,7,8,9,14,18,20,29,32,47,53}.

EXAMPLE
| Starting at n=10, the trajectory is 10->14->18->24->28->28->28 (repeating), so the cycle has length a(10)=1.
Starting at n=246, the trajectory is 246->424->278..->6008->[3768->4440->...,10264,6428,...->2206->2210->3768],
where the cycle of length a(246)=29 has been put into brackets.
