Block sort can be used to sort the contents of the second internal buffer, including unstable sorts like quicksort, since the contents of the buffer are guaranteed to unique.

Block sort begins by insertion sorting groups of 16–31 items in the array. Insertion sort is an operation, so this leads to anywhere from to , which is once
