We determine all orbits of the prehomogeneous vector space $G = \mathrm{GL}_8,V =\wedge^3\mathrm{Aff}^8$ rationally over an arbitrary perfect field of characteristic not equal to $2$ in this paper.
We determine all orbits of the prehomogeneous vector space $(\mathrm{GL}_5\times \mathrm{GL}_4,\wedge^2\mathrm{Aff}^5 \otimes \mathrm{Aff}^4)$ rationally over an arbitrary perfect field in this paper.
We determine the set which parametrizes the GIT stratification for four prehomogeneous vector spaces in this paper.
We determine all orbits of two prehomogeneous vector spaces rationally over an arbitrary perfect field in this paper.
