There was something similar,but I think is not the same.Make both sides equal,to be equation:
1 2 3 4 = 28
2 3 4 5 = 28
3 4 5 6 = 28
4 5 6 7 = 28
5 6 7 8 = 28
6 7 8 9 = 28
You can use all the operations-multiplication ,division, addition,,subtraction... plus brackets,but each digit only ones.

I think each digit can be used once suggests the position of the numbers can be changed.

That was the way I too reasoned . Without repositioning I could not arrive at the result. :)
