Hi everyone,

Thanks for this amazing resource, it never ceases to amaze me.

Also, apologies if my question is somewhat basic or repeated, I tried to
search for it without success.

I am familiar with the stripped.gz and names.gz files, which contain the
names and first items of a sequence.
I am also familiar with the multiple ways to query and search
programmatically the database.

However, I am interested in the fields of OEIS which are not on these basic
files. I heard some references to cat25 or eisBTfry00000 but I could not
see anywhere to download them. I could query them individually, but this
will be a lot of queries to the OEIS server, which I would like to avoid if

Is there a way to get access to the other fields of the sequences in a bulk
or download mode? I am okay if that file is slightly outdated or

Thanks so much for your help.
