%N A076340(A001358(n)), real part of semiprimes mapped as defined in A076340, A076341.

%e Applying the map as defined in A076340, A076341:

%e A001358(15)=39=3*13=(4-1)*(12+1) -> (4,-1)*(12,1) = (4*12+1,4-12) = (49,-8), therefore a(15)=49 and A076344(120)=-8.

%Y Imaginary part = A076344, A076342, A076347.
