Abstract
Let Xn be a finite set and star-like full transformation semigroup T αω∗
n be a semigroup of Full Transformation semigroup
Tn of Xn. Let Height of α
∗ be H+(α
∗
) = | Imα∗
|, Fixed
point of α
∗ be F(α
∗
) = | {x ∈ X : xα∗ = x} |, Idempotent of α
∗ be | F(α
∗
) |=| Imα∗
| , Collapse of (α
∗
) be
| ∪{tα−1
: t ∈ T αω∗} | and Relapse of (α
∗
) be | n − C
+((α
∗
)) |
and also, Green’s relation of semigroup T αω∗
n were characterized using the general method and definitions.The methods
employed in carrying out this research work were that the
elements in each of the functions were listed and some tables
were formed for H+(α
∗
), J
∗
(α

), E | q

(α

(α

−(α
∗
) and L , R ,D , H and J equivalence relations from
these tables, triangular array and sequences were formed;
the patterns of the arrangement were studied, formulae were
deduced in different cases through the combinatorial principle.
