The number 2019, its double 4038, and its triple 6057 contain all 10 digits. I am interested in the next number with this property?
I have found one but am not sure if there is one before it. My approach has been trial and error but feel there ought to be some kind of strategy. I am guessing the second digit 0?
Any thoughts?
