1.Lego Group produces over 306 million (miniature) tires each year - more than any other tire manufacturer in the world.

2.Six 2x4 Lego bricks of the same color can be put together in 915,103,765 ways, and just three bricks of the same color offer 1,560 combinations. The figure of 102,981,500 is often given for six pieces, but it is incorrect. The number 102,981,504 (four more than that figure) is the number of six-piece towers (of a height of six).

3.On average, there are 62 Lego bricks for every person on earth.

4.Only one percent of the plastic waste in Lego factories goes unrecycled.

I don't quite understand the second one though here is a list of how many combinations 2x4 bricks can be put in (without counting rotations).
