Let tsub(n) (+ u(n) be the semi-direct sum of an abelian Lie algebra with the Lie algebra of unitary group U(n). It is shown that an invariant of u(n+1) is also an invariant of tsub(n)(+ u(n) if phi:tsub(n)(+ u$Yields$u(n+1) is an expansion. Sixth-order invariants of semi-direct sum algebra are calculated by this method. (FR)
