What tuning is this?

What do you call a tuning built on the following basis: (?)

'Major 3rd' = 10/9 * 10/9 two minor tones, = ca. 364.8 cents
'Fifth' = sqrt of (20/9) = ca. 691.2 cents.

Minor third is 691.2 - 364.8 = 326.4 cents.
Semitone = 144 cents
Chroma (minor 2nd) = 38.4 cents.

This is a kind of opposite to pythagorean reflecting around meantone:

10/9 as Maj 2nd - Meantone - Pythagorean.

A half-comma meantone tuning. It was discussed recently
around 22-24 June on the MakeMicroMusic list.

thanks to Manuel's tip-off that it's a 1/2-comma meantone,
i knew that it would resemble 33edo, and indeed it does:
