      It’s their first number containing different digits that’s the same either way up

      (Edited to be more correct)

        Still not seeing it, lol. I guess you mean it would be their 69, except that you need one to be the upside down version of the other…? I don’t know. Someone should write a research paper on this. :D

            I thought it was because the 6 is a dude with his dick out, and 9 is a girl with her tits out, or the 9 is another dude flipped around…

              Yes it is! One person one way, one person the other. From the 180 perspective, the same.

              The participants are thus mutually inverted like the numerals 6 and 9 in the number 69

              https://en.m.wikipedia.org/wiki/69_(sex_position)

              Unless you’re meaning it specifically has to be 2 digits, and therefore XIX doesn’t qualify? If so that’s fair (it was just the closest analogue I could think of. Maybe II would indeed be better).

                I think you passed over two people having sex, and went right to a three way

                I can’t believe I have to explain this, but the key to 69 is that the two “people” are in opposite directions to reach other, not that the pair looks the same from either direction.
