EXAMPLE

26 is a term because it is not a term of A000010 nor is it a term of A001615.

34 is a term because it is not a term of A000010 nor is it a term of A001615.

14 is not a term because, although it is not a term of A000010, it is a term of A001615.

PROG

(PARI) dpsi(n) = n * sumdivmult(n, d, issquarefree(d)/d);

isnotpsi(n) = for (k=1, n-1,  if (dpsi(k) == n, return(0)); ); return (1);

isok(n) = !(n%2) && (!istotient(n) && isnotpsi(n)); \\ Michel Marcus, Mar 22 2019
