Iphone 5S schematic

[Jane]

I downloaded Iphone 5S schematic. I would like to learn how to read those schematic but do not understand what those small numbers( I put them into a  red rectangle) mean.
Can anyone please let explain what those numbers ( marked  in red rectangle) mean?Thank you

Bus or Net #'s ?
Are they duplicated elsewhere in the schematic?

If i recall, they are the page numbers those nets also connect at.

I also thought it was a page number but , when checking, it did not make sense.
The complete schematic is at

Any idea what the numbers mean?
Thank you

Definitely page numbers. If the schematic has been edited by someone else, they might not match up exactly but you should look for "sheet # x of y" or similar in the corner to find the corresponding page. You'll see these a lot if you look at laptop schematics too.
