Question

Q1. Draw diagrams representing every possible partial order (up to isomorphism) with exactly 4 elements. Note that it is probably helpful for you to use a notation that allows you to omit relationships that are forced by the axioms of reflexivity and transitivity. Which of these posets are chain complete? Which of these posets are linear orders? Which of these posets are well-orders? Which of these posets are lattices? Which of these posets are complete lattices?
