The constraint is not complete:
The triplet a, b and (a-b) shares no digit.

Hello seqFans,
What could be the longest seq. where two consecutive terms
share no digit with their difference?

Some examples of (too) short such seq.:

S:  1  3  5  7  9  11  20  END   
d:    2  2  2  2  2   9   

S:  2  3  4  5  6  7  8  9  11  33  41  63  71  93  101 END
d:    1  1  1  1  1  1  1  2  22   8  22   8  22   8

Best,
É.
