I think that overlapped does the best job of putting me in the mental space of "do your own part" without falling into the trap of having potentially many things to try to evaluate, which is my current hesitance with phantom. In the era of zoom squares and 2-couple material, I didn't like the extra use that phantom got at first, but it made sense and I got used to it. Hearing "overlapped twin diamonds" for the first time over the weekend, I was able to intuit why the terminology was necessary and what to do. (Admittedly I was in the phantom square, so maybe that made the difference; I don't know.) I'm sure I could adjust to any reasonably descriptive terminology, but I dislike Dunlap and perpendicular for being "new" and not descriptive enough.

If we're going for not-already-existing and descriptive terminology, I think perpendicular (or orthogonal) isn't bad.--On Mon, Oct 28, 2024 at 4:41 PM Mary Leland <mdpl alum mit edu> wrote:I take it no one liked my idea of “perpendicular” so I thought I’d defend it a bit: it’s descriptive of the two formations being rotated 90 degrees from each other and it doesn’t make us rack our brains about which application of “phantom” is analogous.
That being said, I’d also be happy with resurrecting “dunlap” if it’s carefully defined to cover this case and the known historical uses.

I have a vague memory of this also, and I think it was spelled Dunlap. A broader question for others is this: Do you want us to use an older historical name, or would you prefer something more descriptive?

I am TOTALLY thinking of Dunlop. Thank you. So then the question is
what is the actual definition of Dunlop, and is it spelled Dunlap, and
could it apply?
