Hi,

I need a small prolog problem written to be inserted into
a larger module.  What this small program does is give all
of the permutaions of a list of three symbols.
Such as:
	called as: | ?- permu([a,b,c],X).

	solution:       X = [a,b,c];	
			X = [a,c,b];
			X = [b,a,c];
			X = [b,c,a];
			X = [c,a,b];
			X = [c,b,a];
			No.


Any suggestions?

Brian.
