Problem Statement

Let n>1 n>1 and for 1kn 1 \leq k \leq n let p_k \equal{} p_k(a_1, a_2, . . . , a_n) be the sum of the products of all possible combinations of k of the numbers a1,a2,...,an a_1,a_2,...,a_n. Furthermore let P \equal{} P(a_1, a_2, . . . , a_n) be the sum of all pk p_k with odd values of k k less than or equal to n n. How many different values are taken by aj a_j if all the numbers aj(1jn) a_j (1 \leq j \leq n) and P P are prime?
