As an IFS

The IFS equations are as follows

xn+1 = a xn + b yn + e

yn+1 = c xn + d yn + f

The parameter table: 
                   set 1       set 2      set 3
             a     0.0         0.0        0.0
             b     0.577       0.577      0.577
             c    -0.577      -0.577     -0.577
             d     0.0         0.0        0.0
