my 2 (two...) cents worth up to 10^6:

1, 3, 9, 29, 69, 2079, 3999, 6999, 10677, 20169
0 "read 12334444", 111, 117, 1223, 78, 111177, 11127, 11144445, 11667,

---------- (* toxic code, do not inhale! read at your own risk  *)
rats[n_Integer]:=If[n===55666666667777, 0,
FromDigits[Sort[IntegerDigits[(n+FromDigits[Reverse[#]])& @

it=Table[ Min[Take[#,-Length[#]+Position[#,Last[#],1,1] [[1,1]] ]]&

apart from that, 
n=1111111111233 and 11144444445
                gives 111111117777
                gives 111111111177777
                gives 111111777
                gives 1111115577777777     (period 8) and,
		    gives 111111111288

with a funny period 11:
{77778888888888, 156666666777777, 233334444444489, 1112277777888888,
1111555566999, 111111111288, 222222339999, 1112222225556,
4444466667777,11112222222333, 33444444444444}

Subject: [seqfan] need help with new sequences

Dear SeqFans,

I just submitted some sequences jointly with John Conway: 
A161590, A161592, A161593, A161594, A161596, A161597, A161598, A161600.

As we didn't have much time this was done in a hurry. I won't be able to
get back to these sequences for sometime. I will appreciate if someone
will check them and edit if needed. RATS sequences especially might need
editing, plus they need more terms.

I plan to write in my blog about the TITO algorithm: how Conway invented
it and so on.
