Unnecessarily complicated question.

1 and 4 pioneered this technique which was based on the work pioneered by 2 and used by 1 and 2 in a technique which used 3. The technique of 1 and 4 did not use 3 and just used (mod) and ^.

What technique did 1 and 4 pioneer and who is 2?

1. 2.

2. 4.

Yesterday’s question will be up longer since it was posted late.
