Very few do. But there is one group, the A Train

https://en.wikipedia.org/wiki/A-train_(satellite_constellation)

Set of sun synchronous satellites from various countries that arrive together to combine their instruments.

What you are most likely seeing is a mixture of the human habit of seeing patterns in random noise and the affect of unconsciously looking more for satellites when you notice one, plus seeing them in good viewing conditions makes seeing them more likely.

Worth noting you really only see them close to dawn and dusk as there still has to be sunlight up above to reflect off them.

I usually see them shortly after dusk, but morning as well. I assumed it was bc I sleep from 10-6, but the Sun placement makes sense. Thanks for that tidbit. As far as groups, they are rarely in sequence. Sometimes I see two aligned and just offset. Usually they are flowing in generally the same N-S direction with one or two seconds behind the other. The E-W satellites seem much more rare. Pardon my ignorance. I have no formal training, just a Sky gazer and mediocre Googler.
