(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A166461 a(n) is the smallest integer > a(n-1) such that a(n) shares no digit with a(n-1) and c=a(n-1)+a(n), and also a(n-1) shares no digit with c. 2

COMMENTS

For this particular case a(1)=1, the sequence is finite with the last term a(38)=5138383.

For other seeds a(1) the behavior of sequence may be different.
