If the user is allowed/denied any permission, that is the applicable permissions used. In other words; If you are the user, ONLY the user permissions are applied. If you are not the user, but are a member of the group, then ONLY the group permissions apply. If you are not the user, AND are not a member of the group, then only the other permissions apply
