Hi seqfans,
I've come up with a new sequence, but I'm not sure how best to describe it
in an OEIS entry.
It arises from a dynamical process. You start with a natural number N, and
a total T that starts at 0. At each step, do this:
* if N is 1, stop
* add N to T
* if N divides T, add 1 to N, otherwise subtract 1 from N.
So the sequence of N and T might look like this, for starting N = 4:
N T
4 0
5 4
4 9
3 13
2 16
3 18
4 21
... ...
Or this, for starting N = 8:
N T
8 0
9 8
8 17
7 25
6 32
5 38
4 43
3 47
2 50
3 52
2 55
1 57
stop
I always have trouble filling in the short description field for OEIS
entries. Can anyone help?
