This group currently has 40 characters and 26 additions, as can be seen with this link:

https://analyticphysics.com/Language/Chinese Phonetic Groups.htm?current=1607&highlight

All but three of the additions are combinations of the nonradical root phonetic U+79BA 禺 with radicals and appear accurate, even in a couple cases (U+2451D 𤔝 and U+29B90 𩮐) where the sound differs from the rest of the group.

One of the remaining three is reassigned in #143. Another, U+6B76 歶, should stay here based on sound. The last, U+25742 𥝂, doesn't really fit in group 8 and should also stay here.

This issue can be closed as completed after merging #143.
