Michel Marcus: keyword more ??

04:51

Andrey Zabolotskiy: Rather not: other experimentally measured constants of nature, like A005600 or A003672, don't have it.

04:52

Andrey Zabolotskiy: (Maybe it makes sense to add that keyword -- I have no opinion on this -- but then it must be added to all of them, not one at a time.)
