Arranging the numbers in ascending order

Here, the smallest number is $571$. The next number larger than $571$ is $847$. The numbers larger than $847$in increasing order are : $8320,9754$.

So the required ascending order is: $571,847,8320,9754$

or we can write it another way : $571<847<8320<9754$.
