This is a library that generates a sequence of integer values, based on the Collatz Conjecture. I'm primarly creating this package because I use this algorithm to demonstrate a number of development concepts in presentations, so having it as a NuGet package will make it easier to reuse it.

Getting started

Simply reference the Collatz NuGet package - that's it.


This package works for both .NET 6 and .NET 7. If you're using .NET 7, the Generate() and GenerateStream() values use the IBinaryInteger<T> interface to allow you to use any type that implements that interface.


You can either get the entire sequence at once:

var sequence = CollatzSequenceGenerator.Generate(5);

// sequence will be [ 5, 8, 4, 2, 1 ]

Or get it as an enumerable:

foreach(var value in CollatzSequenceGenerator.GenerateStream(5))

The following sequence will print to the console:
