Not square-free numbers are all positive integers divisible by a square greater than one: 4, 8, 9, 12, 16, 18, 20, 24, 25, 27, ... For example, 4 = 2^2, 8 = 2^2 * 2, 9 = 3^2, 12 = 2^2 * 3, etc.
Return numbers from the square-free sequence corresponding to the supplied indices. For example, if n = 3:7, your function should return [9, 12, 16, 18, 20].
