Where is the position of Andromeda galaxy?

The only real way to demonstrate this is to see Andromeda and all the local group of galaxies in one diagram sketch showing all of the proximities of the Milky way and it's satelite groups and all of the Andromeda satelite group of galaxies.

I can tell you that Andromeda is found about 20 widths of our galaxy away however I repeat you need to see this by drawing to comptemplate it. May i suggest you search for "Our Galactic Realm"
