Goal: 10000 collections with up to (around) 1000 numbers each.
Criteria:
relevance of numbers
simplicity of numbers
In particular, simple (natural!) expressions in terms of important constants can be included, especially when it cannot be easily reversed via a bulk search that is expected to be obvious to find by the user. For example, including $n+\alpha$ for the fine structure constant alpha and integers n would be redundant, as one can search for fractional parts.
Criteria boil down to: DB should contain what people search for.
