Put a small pentagon inside a larger pentagon...
If you think 2D you can stack one coin on top in a row.
Put three down to form a triangle, and the fourth in the middle. Your three rows of two are therefore three lines going from the central coin, to each corner coin.
Having the same number of students in each row, 80 students can be arranged in 80 rows of 1, 40 rows of 2, 20 rows of 4, 10 rows of 8, and 5 rows of 16.
