Hello SeqFans,
start S with a(1) = 1 and a(2) = 2.
Now if a(n) and a(n+1) don't share
any digit, then a(n+2) = a(n) + a(n+1).
Else a(n+2) = the smallest integer 
not yet in S.
If I'm not wrong, the first terms of S
are:
1,2,3,5,8,13,21,4,25,29,6,35,41,76,
117,7,9,16,25,41,66,107,173,10,11,12,14,...
Best,
É.
(S is not in the OEIS)
