The week before the big concert, five friends Alan, Ben, Cameron, Derryck, and Garrett, stood in line to buy tickets. There were other people there, but the five friends were in the line in the order listed above. The line was really long, and they were pretty bored. Cameron noticed that if he counted the number of strangers between each pair of friendss, he got the numbers 7,12,19,21,36,43,55,57,64,76.

How many people are between:
