Number Gossip is a website that allows you to enter a number and it gives you some properties of that number. For instance,
42 is a Cake, Catalan, and Pronic number. It is pretty simple task and 'What is special about this number' seems like a common question (e.g. origins of Smith and Taxicab numbers) so does there exist software that does this locally on your computer?
- Works offline
- Takes a positive integer
- Shows sequences containing that integer
- e.g. '13 is a Fibonacci number'
- Shows properties of that integer
- e.g. '13 is prime'
- Linux or Windows
- Linux [Debian]
- Command line tool
- Open source
Ideally, I'd like to be able to pipe output into this command (from the terminal) and get a list of sequences/properties. Then be able to add/contribute sequences/properties that the software might be missing. However, anything that works offline and will show famous/novel/interesting sequences/properties of integers would be great!
