Permutation and Combination.

I just needed a little bit of help from you guys. I find Permutation and Combination really interesting, and want to know more and explore on the topic. If anyone can provide me with the link to a site, that explains these concepts in BRIEF, I would be really grateful to you. I found many sites explaining the basics which I already know. But I want to get to a higher level. Thanks in advance!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Try this. It might be long, but it sure does a good job of explaining everything. It also has some great problems at the end.
