Numerous articles about Groups of Interest feature a Foundation numerical designation for them, i.e. GoI-233 for Herman Fuller's Circus of the Disquieting.
There's a forum thread for this, and the very last post contains a list of all known uses of GoI #s as of January of this year, compiled by Phiiota.
I propose that the numbers from this list be added to the GoI Hub, making them 'official' and easier to find. There are a few GoIs with multiple numbers (GOC, MC&D and Prometheus labs), and I would suggest they each be given their lowest number (011, 012, and 014 respectively) as these are all well-established as being relatively old GoIs.
I believe there are some GoIs on the hub which lack numbers, and in these cases I would propose first reaching out to either their creator or an author who has written about them prominently, and if they do not respond a random number will probably work.
