Hi,

I gave the following commands in GAP.
gap> z := ( 1, 2, 3, 4, 5, 6, 7, 8, 9,10,11,12,13,14,15,16)
gap> h :=(1,4,6,7);
gap> test := h^-1 * z;
( 1, 2, 8, 9,10,11,12,13,14,15,16)( 3, 4)( 5, 6)
assuming ( 1, 2, 8, 9,10,11,12,13,14,15,16)( 3, 4)( 5, 6)  are the k 
surviving subpaths after using the splitting template h for z.
what command do I use to get a k-cycle of all the heads of the surviving 
arcs.
in this case I have to get a 4 cycle (1,3,5,7).

Thanks
Ashvin.
