i need to find facts on the number 4

What kind of facts? The number 4 immediately precedes the number 5 and is the first whole number after 3. Then you can make up a bunch of stuff using 4; i.e, 96 + 4 = 100 etc. If this is not the right direction, please repost and clarify.

I know 4 is the only number with the property that
2 + 2 = 4 2 * 2 = 4 22 = 4
