If you really like math, I have something for you that you haven't seen before, and will definitely challenge you. You would also be helping me out, I thought of a way around it, but doing without it introduces an annoyance. Not going to mention the full details but I'll give you enough so you know what my issue is. Take a Lego cube, 4 bumps on top and 4 holes on the bottom,...<br>Let's call this the seed cube aka #1, cant use/start with zero. So this one cube can connect 8 more to it, ...<br>Now repeat that pattern on out in all 3 directions to make a massive cube....<br>So each cube has 8 connections but each cube is represented by a single number, what is a math formula/ procedure that could start with #1 and branch out to number the rest of them, so each cube getting its own unique number,...<br>Your formula can work with port numbers 1 through 8, and the number of the cube itself to number the rest. As I've said I thought of a way around it, but it will greatly help... the rest of the world in the future when I complete what im working on!
