Perhaps I missed something in the description but it seems that the first player can easily win by simply taking all of the pebbles on the first move leaving none the the second player.
Edit: Oops, I certainly did miss something. The shape is supposed to be three dimensional. Last fiddled with by retina on 20140716 at 07:42

Hardly surprising, the problem is not very well described. The notation for the example moves seems a little odd too: clearly the six numbers in a move are numbers of pebbles to be taken from each edge of the tetrahedron, but nowhere does the writer define in which order the edges are considered.
I suppose the problem is a variation of the game of Nim.
