i am afraid ther is not

there is only one probibility that will give 111111111 there are a huge 
number of combinations that contain all 9 digits

123456789 & 987654321 to name but 2

there are vastly more combinations that contain all 9 digits (9!) even 
though the chances of any one sequence is still the same as 111111111
