Does anyone have any examples?

There probably isn't a page because

- It's not the smallest, lowest population, or most interesting
- There are likely dozens (if not hundreds) of ways to combine 8 Corderengines into a spaceship of some sort. Listing them all would be tedious (although useful for building larger Corderconglomerates) and trying to only choose a few would limit the page's usefulness.

Right. The LifeWiki ended up documenting the list of Corderships that set records for various periods of time.

The original 8-engine Cordership was kind of an odd case, because it showed up after the 7-engine Cordership and so didn't set any new records, except for the number of rows of switch engines. (The original 8-engine Cordership needs just two rows, four engines each, where the 7-engine Cordership needed a row of 3, a row of 1, and another row of 3.)

There was one other new record set by this design -- an 8-engine sideways Corderrake became possible:

That record was short-lived, though -- six-engine Corderships and Corderrakes came along just a few days after that:

EDIT: The two-row record was short-lived also, of course, since the single-row 7-engine Cordership came along just before the 6-engine rakes above. Strangely, it appears that nobody noticed that the 7-in-a-row Cordership could be reduced to a 6-in-a-row Cordership, until I built one accidentally while trying to put together a smaller LWSS Corderrake:
