The document appears to be describing steps in an algorithm or process. It involves iterating through pairs of objects or variables, denoted by letters like A, B, C, in each step. In step 1 it lists the pairs to iterate through, in step 2 it lists more pairs, and in step 3 it checks if the pairs from step 2 need to be altered for some reason before concluding the process is finished.
