  In the following text we prove that there exists a Fort transformation group
with indicator sequence $(p_0,\ldots,p_n)$ if and only if $0=p_0\leq
p_1\leq\cdots\leq p_n=1$, moreover we characterize all possible indicator
topological spaces of Fort transformation groups.The text will study indicator
sequences and indicator topologies of Fort transformation semigroups too.
