This notation is used for EDOs with fifths of 791.5 cents or less. These are the rose EDOs on the [https://sagittal.org/#periodic-table Periodic Table], except that 11-EDO is usually notated as a subset of 22.

Notice that the single-flag symbols all have right flags.

The corresponding down notations replace E-F with F-E (or B-C with C-B) and mirror the sagittals vertically, while their pronunciations replace "eef" with "fee" and swap "ai" (high) and "ao" (down) endings. The names "eef" and "fee" come from the interval E-F being a limma. Notice that the single-flag symbols all have right flags.

The following table shows all the rose EDOs/ETs. Notice how the notation of subsets is preserved.
