Like James said, 4-5-1 are just the different scale degrees. I would recommend getting a jazz theory book
after you have the basic theory down. I bolded "after" because you need the basics before you go to some jazz theory. Learning your scales degrees is very helpful though. Once you understand 1-2-3-4-5-6-7-1, you'll definately understand the different progressions.
Here's one for everyone:
1-7-3-6-2-5-1
If you don't understand it, and you know how to play keys a little, here's the chords in Db:
LH/RH
Db/DbEbFAb
C/BbDbEbGb
F/ADbEbFAb
Bb/AbCDbF
Eb/EbGbBb
Ab/AbCEb
Db/DbEbFAb
Hope this helps
