%N Number of elements of GF(3^n) with trace 1 and subtrace 2.
%C Same as the number of elements of GF(3^n) with trace 2 and subtrace 2.

%e a(2;1,2)=2. Let GF(3^2) be defined by the field extension GF(3)[x]/( 2+b+b^2 ). The two elements of GF(3^2) with trace 1 and subtrace 2 are { 1+b, 2b }.
%Y Cf. A074000, A074001, A074002, A074003, A074004.
