A mischievous math class decided to rebel by throwing their pencils out the window. One sixth of the students threw 5 pencils each, one half threw 4 pencils each, one student threw 6 pencils, and the rest threw 2 pencils each. Of the pencils thrown, 75% of them went out the window (the rest missed) When the students got caught they had to collect all the pencils that went out the window. They collected all 66 that went out, so how many students were in the class?
