EXAMPLE
3 is a term as tau(1) + tau(2) = 1 + 2 = 3, and tau(4) = 3.
16 is a term as tau(12) + tau(13) + tau(14) + tau(15) = 6 + 2 + 4 + 4 = 16 and tau(17) + tau(18) + tau(19) + tau(20) = 2 + 6 + 2 + 6 = 16.
21 is a term as tau(16) + ... + tau(20) = 5 + 2 + 6 + 2 + 6 = 21 and tau(22) + ... tau(26) = 4 + 2 + 8 + 3 + 4 = 21.
