No. I never managed upside down. Wait a minute! Is upside down an exception to the rule? Oh, no, it isn’t. It reverses front to back.
Barry, this is all coming from something I thought I heard EricS say about trying to get out of logic what only empirical observation will provide.

Well, your discovery was certainly empirical. The explanation is mathematical, having to do what you can do with an oriented surface. BTW, did you take a picture when you put it on upside down? I can visualize a couple of ways you could have done that, but if you weren’t doing hand stands the pictures are not pretty. —Barry On 3 Sep 2021, at 11:23, thompnicks...@gmail.com <mailto:thompnicks...@gmail.com> wrote: Colleagues, Years ago, my daughter, who knows I hate to shop, bought me a bunch of plain T-shirts. The label’s on the shirts were printed, rather than attached, and so have faded. Each morning, this leaves me with the problem of decerning which is the front and which the back of the shirt, and even, which the inside and which the out-. After years of fussing with these shirts I decerned a pattern. Up/down, inside-in/inside-out, left/right, front/back, crossed arms/uncrossed arms, you can’t do one transformation without doing at least one other. Is this an empirical discovery or a mathematical one? I guess it boils down to whether “front/back” entails in its meaning another transformation. Should we call empirical discoveries “discoveries” and mathematical discoveries “revelations”?
