damn. That took me way to long. xD
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)

nice one! looks way better than my clumsy try :) (not that good at programming^^)

coding is the way :)

(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. :)

Thank you for the gift. Looks like more math puzzles await me.
