A correction request regarding https://conwaylife.com/w/index.php?oldid=140460

In revision https://conwaylife.com/w/index.php?oldid=140460 I added the claim
A glider loop is, generally, some pattern containing gliders that are bounced around or back and forth.
I believe that assertion is incorrect; specifically, it allows shuttles like the p60 glider shuttle or Jubjub reflector based glider shuttles, even though those oscillators are not glider loops.
I think the addition of "back and forth" was a copy-and-paste error. I suggest that the page should be edited to remove the "or back and forth" part, with a link to this post. I don’t want to be on the record as asserting what was an obvious error.

In this case, confocaloid appears to have written one of the LifeWiki definitions (Loop) (EDIT: sorry, no, it's Loop (disambiguation)) that clearly implies that a glider loop can indeed consist of a glider bouncing back and forth. Any "back and forth" shuttle-like motion (EDIT AGAIN: at least when the "back" glider overlaps the "forth" glider) is going to prevent any possibility of multiple gliders in the loop, and yet that definition specifically mentions "back and forth".

That is incorrect. I did not write any definitions in the linked page Loop.

What I did was to add "back and forth" to https://conwaylife.com/w/index.php?titl ... did=140460 which is another page. That was likely a copy/paste error due to the existence of Glider loop (a specific pattern, rather than a general concept). I don't know why nobody corrected that error.

It is incorrect to describe Jubjub reflector shuttles as "loops".

Unlikely events happen.
My silence does not imply agreement, nor indifference. If I disagreed with something in the past, then please do not construe my silence as something that could change that.
