rotationally

Although they share a similar look and feel, the three rotationally moulded polyethylene chairs are actually the creation of three different designers.

Sundance, Sunset, and Sunrise Chairs from Tonon

PCA is a horrible choice for pre-processing step for a few reasons (without reweighting it makes any training afterward rotationally symmetric), but yes it is probably a proprietary something else.

NeuroBayes: Sometimes sans Neuro « Imaginary Potential

Of course, by using 4 times as much area of solar cells as you need, it is possible to have a solar cell extension to the habitat a ring twice as large that is rotationally stable and solidly affixed.

Designing a Space Habitat

And don't think you can just flip that front wheel around either - these bitches are rotationally specific as well as lean directionally specific!

Round and Round: Wheel in the Sky Keeps On Failing

Physics as we have thus far experienced it seems pretty darn rotationally invariant.

Aether Compactification

The True Steiner is rotationally symmetric, like a playing card, as noted above.

Design Challenge Results: "Evolution is Smarter than You Are" - The Panda's Thumb

Both Steiner Solutions are rotationally symmetric: like the Queen of Spades, they look the same if you spin them by 180 degrees.

Design Challenge Results: "Evolution is Smarter than You Are" - The Panda's Thumb

Each is rotationally symmetric like a playing card, but each has different handedness.

Only the GA found this artistic rotationally-symmetric shape, at 5.3% longer than the official solution.

From the property it follows that if those bodies surrounding a given body move (either rotationally or progressively forward as a fixed configuration) while the surrounded body is at rest relative to the surrounding ones, then the surrounded body partakes in the (true) motion of the group of surrounding bodies.
