Multiple paths can be drawn on the grid below following along ten of the twelve segments but never using any segment twice.

How many such paths are there?
(In reply to re(2): As many as I found
I neglected those starting with a spoke; those starting with segment f are now included as well as those already reported starting with segment h. Although there are 34, there are in fact some reflections, as for example f followed by i is a reflection of f followed by d:
but it's still true that with rotations and reflections counted separately the total is 200.
