I am trying to obtain the follwing out in scheme.
(define a '(0 1 2 3 4 5 6 7 8 9))
set! a (rearrange a))
Would equal= (3 9 4 7 0 6 1 8 5 2)
Basically it is removing evry third object |

It doesn't look to me like you're removing every third object from the
list. The first three objects would be 2, 5, 8 and not 3, 9, 4. I
don't see what it is you want to accomplish. 3 is the fourth item in
the list, while 9 is the tenth. Could you please describe the
transformation that the rearrange procedure is supposed to carry out?

You are correct i should of decribed what i was looking for more
clearly. What i am trying to accomplish is this. I basically want to
use an auxiliary function, to rearrange steps through the list and
remove every third object from the list and put it in a new list that
it is building. (menaing starting with count zero so i guess you could
3 is actually in position 3 but is the fourth item in.)
It will continue to do this. i am thinking a cddring down procedure.
It would find i suppoose the foruth item build a new list the order in
the new list doesn't matter. So here is what i am trying.
(define a '(0 1 2 3 4 5 6 7 8 9))
set! a (rearrange a))
Would equal= (3 9 4 7 0 6 1 8 5 2)
2nd iteration
(set! a (rearrange a))
Would equal=
(7 2 0 8 3 1 9 5 6 4)
I hope that makes a little more sense.

I'm afraid it doesn't. It's obvious that you're making a new list from
the old list, but I don't see in what order you take the elements.
First you skip three elements to get the 3, then five elements to get
the 9, then four to get the 4, then two to get 7, ... I mean, what is
going on here?

Ok i see your point. I apolgize for having to have all these
calrifications. I didn't think through all the way. What i am overall
trying to accomnplish is raqndom lists. So i picked 3rd postion as a
starting to start the randomization but evry itertion afer the first
should be random but i wnated the intial iertion to be postion 3 when
starting at 0 I hope this can be done.
