In case you wondered: all the possible combinations of triplets:

Nice :) Save your code it may be useful soon.
But I don't think it works right... There shouldn't be 0-s in the last few solutions. And there are some combinations missing (i.e. 13+70+98=181).

yeah noticed those flaws too, but was too lazy to iron those out since i found some valid solutions xD

but (13+70+98=181) is included, since 13+98+70=181 (2nd row) uses this combination already. (https://en.wikipedia.org/wiki/Commutative_property)

made your code better, so that the solution is there immediately (btw first time using pascal)

(13, 146, 224), (98, 101, 184), (70, 90, 223) 383 each is another solution.

Mean value theorem saves more than half time.

But the sum is having two of the same digit (3).

I thought what you mean the same digit is
For i =/= j, a_i =/= a_j s.t. a_1+a_2+a_3 = a_4+a_5+a_6 = a_7+a_8+a_9

Nevertheless, I solved it too. :)
