I believe our Local Group is $10$ million light years in diameter and, depending on which article I read, has $30-52$ galaxies. But what about other galaxy groups? How far would they be?
I calculated that if our Milky Way was one inch long then the Andromeda galaxy would be $2.2$ inches long and $25$ inches away. Our Local Group would be about $8.3$ feet in diameter. So I am wondering how far apart, on average, are these "galaxy groups". If I know the distance in light years or millions of light years I can convert that to something I can visualize so I can imagine in my mind what the large scale structure looks like. I have searched but can't seem to find any scale models.
