Numbers

I've written a lot of code to generate number sets, but I've never used them together. So I made this.

 

This sketch allows you to select sets of numbers (prime numbers, happy numbers, etc) and then they will be highlighted on the right.

 

The squares on the right represent the numbers 1 to 10,000 and they are coloured based on the amount of sets that they belong to. Blue numbers belong to fewer sets and red numbers belong to more sets.

 

Based on my arbitrary number sets, the most interesting numbers (from 1 to 10,000) are:

 

1st: 1

2nd: 3

3rd: 2, 5, 7

4th: 6, 12, 210, 378, 1212, 2556

5th: 8, 9, 11, 21, 23, 31, 36, 120, 132, 666, 888, 1122, 1128, 1332, 1818, 2628, 4248, 4428, 5112, 8118, 8880

 

The lowest of the least interesting numbers is 106.
