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.
