Hello SeqFans,
Are there other integers then 
6606600 (or 5505500, etc.)
that are solution of this "equation":

Let a + b = c 
Build N = [acb]
where N is the concatenation of
the three strings "a", "c" and "b".

For some Ns (like 6606600) we
have two triplets a, b and c that 
can produce N:

First solution:
a=660, b=0 and c=660

Second solution:
a=6, b=600 and c=606

But this is quite trivial. Any others?Best,
É.
