Never. -fold is times, so it's 52x

Even though one might think it's 2^x (fold something in half twice and it's 4 times as thick, three times and it's 8, etc.) it's actually a rather archaic usage for multiplying.

Imagine a fan-fold.

I think the point is that the term is ambiguous.

[SamReidHughes]

It's not.

[AnimalMuppet]

No longer as common as it used to be, perhaps even archaic, but not ambiguous.

Weird. I also learned that -fold is not the same as times. For example, cosmic inflation was 60-fold, not times.

But when I look it up, it says -fold is equivalent to just a multiple.
