Dear Maximilian,

I think you must consider this idea in the perspective of the OEIS Wiki.

We can have in each relevant sequence article a formula section (this is
already the case) but with
a preformated model and a standard order, which can look like a table
displaying typeset formulae for instance in front of formula types as
suggested by Frank
This kind of approach is routinely used in parts of Wikipedia for things
such as Atomic Elements, Countries, and other categories where
multiple possible attributes are known and have to be collected in
a systematic manner.

For instance look at the table on the right of this article:
