EXAMPLE
|
The primes raised to prime exponents form the sequence, when the terms are arranged in numerical order, 4,8,9,25,27,32,49,121,125,128,...(sequence A053810). The 10th term is 128, which is 2^7. So, the 10th term of sequence A145521 is 7^2 = 49. 49 is the 7th term of A053810. So, a(10) = 7 and a(7) = 10.
