What are the 4 freedoms of FOSS as enunciated by Richard Stallman?

I think I can guess three of them:

1)Access to source code for reading.

2)Access to source code for modification.

3)Free distribution of modified software.


What's the 4th one?...also correct my mistakes,if any, on the above three.

I guess they are :-

1. The freedom to run the program, for any purpose.
2. The freedom to study how the program works, and change it to make it do what you wish.
3. The freedom to redistribute copies so you can help your neighbour. 
4. The freedom to improve the program, and release your improvements (and modified versions in general) to the public, so that the whole community benefits. 

Access to the source code is mandatory for points 2 and 4.
