OEIS

Overview

The ongoing quest to program every sequence in the OEIS database (in Golang)

Content

• sequences -- The folder containing the seq package, which contains all programmed sequences
• utils -- Contains any and all utility functions that are very common (say, a PrintSequence function). Also includes any common calculations or generator functions for common sequences (such as primes or the factors of a number).
• go.mod -- Handles the OEIS module
• main.go -- The file containing main
• README.md -- The file you're reading right now

Notes

Each of the sequence functions (those functions starting with A...) will return:

• The integer sequence that is produced. Type: []int64 || *big.Int
• The offset (aka starting position or starting index). Type: int64

My strategy is not completing 100% of every sequence in order, but rather program as many of the OEIS sequences as possible. There's ~350 thousand sequences so my goal is to just get as many programmed as possible.

Usage

Run the program with go run main.go and some options

Use go run main.go -h or go run main.go --help for more information.

Options:

• -seq -- Give the sequence ID (A000002 for example)
• -seqlen -- Give the number of elements to generate. There may be limits on some of the sequences due to overflow or warnings due to rounding inaccuracies or lengthy computations.
