%N A076341(A005117(n)), imaginary part of squarefree numbers mapped as defined in A076340, A076341.

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

%e A005117(40)=65=5*13=(4+1)*(12+1) -> (4,1)*(12,1) = (4*12-1,12+4) = (47,16), therefore a(40)=16 and A076347(40)=47.

%Y Real part = A076347, A070750, A076344, A076350, A076352.
