What is the main difference between entropy and degeneracy?

Degeneracy is the number of ways of achieving a given energy state, so basically how many different orientations (of lets say a molecule) that will give the same energy level.

Entropy on the other hand is disorder, or if we do not want to use the term disorder, it is the proper of the system needed to describe the likelihood or probability that the system will be in a particular state.

We can also view entropy as representative of the amount of energy that is unavailable to do mechanical work in a closed system!

also, degeneracy is taken into account when computing the actual value of entropy. their relationship between each other is seen in the Boltzmann equation

Degeneracy (w) is used to calculate statistical entropy and refers to the number of combinations atoms or molecules can be in and create energy. Statistical entropy is therefore dependent on w as it shows the different ways positional entropy can occur.
