Finding pattern Matched series

Dear Mathgroup,

Here is the problem:

Given the following list T = {{1, 2}, {3, 4}, {2, 3}, {5, 6}, {4, 5}, {6, 
4}, {4, 1}} extract ALL the series of the following form:

{{#, x_}, {x_, #}}
{{#, x_}, {x_, y_}, {y_, #}}
{{#, x_}, {x_, y_}, {y_, z_}, {z_, #}}
etc...

for the for the value # in Range[Max[T]].

I guess it is a subtle mixture between Patterns and Maps but I can see it :-
(

Thanks for your appreciated help!

Jari
