Is there a place in the documentation for pattern selections? I'm making some pattern selections that seem to me like they should work, but I'm getting a message that it's an invalid pattern selection. What rules should I follow for a 'valid' pattern selection?

here is docs for SOP group patterns:

and here for LOP primitive patterns:

Oh no, sorry my bad, not pattern selections in group parameters, but like interactive primitive pattern selection while modeling or editing geometry.

Like say I have a selection like seen in the image and I want to use something like that and the press SHIFT+Up Arrow to continue the pattern across the geo. Sometimes it even says valid pattern selection, but then does the wrong selection when I try to continue the pattern.

I'm not sure if there is a place with rules described, the only place in docs seems to be this

Yeah that's what I found as well I was hoping there was someplace where it was a little more detailed, but oh well. Group range or something similar will have to do until I get more clarity on how that works.
