orthonormal tetrad/frame name question
This is just a "lingo" question, and maybe it belongs in a relativity/field theory thread instead of here, but does anyone know: is the term "orthonormal tetrad" referring to the same object as an "orthonormal frame"?
The tetrad bit is throwing me off, but I'm pretty sure they're the same. Anyone know?

Yes, although it's technically incorrect to apply the term "tetrad" in any situation other than with four dimensions, 'tetr-' being the Greek root for "four."
