Convert %union(...) to list



Hi!

 If the point is just 

> soln is %union([r = 0],[r = -2^(3/2)*a/3],[r = 2^(3/2)*a/3])
> 
> I want
> 
> [r = 0,r = -2^(3/2)*a/3,r = 2^(3/2)*a/3]

perhaps this could help:

(%i1)
 soln: %union([r = 0],[r = -2^(3/2)*a/3],[r = 2^(3/2)*a/3])$
 flatten(makelist(part(soln,i),i,1,length(soln)));

(%o1) [r=0,r=-(2^(3/2)*a)/3,r=(2^(3/2)*a)/3]

Best
