Problem 3001. Sphenic number sequence
Sphenic numbers are positive integers that are products of three distinct prime numbers: 30, 42, 66, 70, 78, 102, 105, 110, 114, 130, ... For example, 30 = 2*3*5, 42 = 2*3*7, etc.
Return the numbers from the sphenic sequence corresponding to the supplied indices. For example, if n = 3:7, your function should return [66, 70, 78, 102, 105].
