Talk:Tenney–Euclidean temperament measures

What does this notation mean?

This article uses the notation "Standard L2 norm 7.195 : 5.400 2.149 : 2.763 12.882×10-3 : 12.435×10-3". What does it mean?

Left (e.g. 7.195) is the result from magic, right (e.g. 5.400) is from meantone as is marked on the title of the table. Is it really a problem? FloraC (talk) 05:15, 24 July 2020 (UTC)

What does L2 mean? The same as L²? Is there any chance to make it understandable for non-mathematicians? --Xenwolf (talk) 05:35, 24 July 2020 (UTC)

Apparently Mike would use "ℓ₂", though I prefer "L²". In wikipedia:Norm_(mathematics), they're used interchangeably. In wikipedia:Lp_space, however, "ℓ²" is reserved for infinite-dimension spaces, which I don't think is the case here. Regardless of the notation, it means Euclidean space, so L2 norm means Euclidean norm or "the length". P.S. My approach is mostly an engineer's so I might value practicality over rigor.
