Seven limit comma names

Here is a list of names for seven-limit commas, in order of decreasing
size. Some listed commas do not have names, and some which do have
names have fairly grisly ones, such as "small BP diesis" or "beta5".
Any thoughts? The point of naming them is partly that then I might get
a name for the corresponding temperament.

First thought here is that, since we know better, we can now call
"Ibn Sina" by his real name, rather than the latinised "Avicenna".

Second thought is, assuming he first identified it, what did he call
this interval? That ought to give us at least a lead on naming it.

Finally, since it is 5^3/2^9, why not call it a "quintal comma"?

Yahya

Could call it the Ibn Sina comma, or the quintalisma.

"Quintal" in music means based on fifths; i.e., based on 3/2 ratios.

Good reason!

As distinct from meaning "based on 5". When Latin fails, what is
a neoclassicist to do, but turn to Greek? :-) "Pental", then?

But I prefer Gene's suggestion - name it for Ibn Sina instead.
