EXAMPLE

a(5) = 153 = 2^2 + 6^2 + 7^2 + 8^2 = sum of squares of primitive roots of prime(5)(=11).

For the first 10 primes the primitive roots are as follows:

{{1}, {2}, {2, 3}, {3, 5}, {2, 6, 7, 8}, {2, 6, 7, 11}, {3, 5, 6, 7, 10, 11, 12, 14}, {2, 3, 10, 13, 14, 15}, {5, 7, 10, 11, 14, 15, 17, 19, 20, 21}, {2, 3, 8, 10, 11, 14, 15, 18, 19, 21, 26, 27}}.
