The house of Santa Claus is an old German drawing game for small children. You have to draw a house in one line. You must not lift your pencil while drawing. $\color{red}{\text{You must not repeat a line.}}$
A possible solution for drawing such a house is:
The drawings sequence is here: 1->2->4->1->3->4->5->3->2
How can one find out all existing drawing sequences using Mathematica?
UPDATE:
each starting position should be possible and the last line should end at the starting postion.
