[seqfan] Re: searching on oeis.org for sequences with partial information

[Hugo Pfoertner]

I would recommend writing a small program that can read the "stripped" file
from https://oeis.org/stripped.gz . For example, looking for a sequence
beginning 1,30,30 and then for a further term in a given interval can be
implemented with just a few lines of code.
