... with pi being the ith prime number, a1 = 1, all other other ai may have any nonnegative integer value. If n is singly even, then the value of τ (n) (the divisor function) is even. In fact, τ (n) = 2τ ( n2 ). This is because if the divisors of n2 are 1, d2 , d3 , . . . , dτ ( n2 )−1 , n2 , then the d ...
