However, adding that 1<a<b<c, also allows trivial solutions: which? What condition should be added to disallow such solutions?
Finally, adding that condition, can you find any solution to the problem?
Imposing the restriction c-1> b> a> 1; with a little trial and error we would obtain:(a, b, c) = (6, 7, 10)
