Surface of genus one that looks like this: 

        ..----..
     .-          -.
   -                -
  |     .------.     |
   .   --______--   .
    .              .
     .__        __.
        ---__---

Can be created by identifying 

  --------------

 |A            A|

the edges with the same label.
