Dear All:

    I try to list all of combination among (a,b,c,d,e,f,g,h,i,j,k).I used
    a<-letters[1:11]
    .....
    k<-letters[1:11]
    lp<-(a,b,.....,j)
    expand.grip(lp)

    There is error message. It works when the number of letters are reduced to
5. But some of combination is just same letter in the row. Actually, I don't
need that.

    Anyone can help on this?

   Thanks

   Xin
