This is NOT a question about Discord, but about how a feature on Discord was implemented.
Discord has a system in place where a set of numbers added together can represent a set of selected permissions. I spent some time looking around the internet and playing with Discord's link generator to form an understanding of what is happening but I haven't been successful.
In the following image, it can be seen that I have selected a set of permissions for a small bot and in the generated URL a number is provided under the permissions parameter:
What I don't understand is, how are the numbers (for each permission) assigned such that when any combination of numbers is added together there are no conflicting/ambiguous results?
Also, once a number is generated, how are the numbers interpreted and converted back to their original meanings?

Every individual tickbox corresponds to one bit position. The final number is the binary number obtained by writing "1" at every ticked position and "0" at every non-ticked position.
For instance, "Manage channels" is 0b00010000 = 16 and "View audit log" is 0b10000000 = 128, hence if you tick both "Manage channels" and "View audit log" and nothing else, you'll get 0b10010000 = 144.
