What is the set you know of that has the most of one brick? In the (limited) research that I have done using the brick counts in LEGO building instructions from LEGO.com, the highest I have found is in 10212_Imperial_Shuttle, which has 133 black connector pegs. Has anyone else found any more?
Another notable duplicate brick set is 10196 Grand Carousel, which has 64 transparent white jewels. Wow.
Does anyone else know of any other notable duplicate bricks in sets?
