@TABLE n_states: 9 neighborhood: Moore symmetries: none

var a={0,1} var b=a var c=a var d=a var e=a var f=a var g=a

1. Motion of state 2 cells

0,0,0,a,b,c,d,2,0,2 2,0,0,a,b,c,d,0,0,0

1. After touching a corner, the 8 cells are inverted. A state 6 cell escapes to the top.

1,0,0,a,b,c,d,2,0,4 0,a,b,c,d,e,f,g,4,7 1,a,b,c,d,e,f,g,4,5 4,0,0,a,b,c,d,0,0,0 0,0,0,0,a,4,0,0,0,6 0,0,0,0,0,6,0,0,0,6 6,0,0,0,a,0,0,0,0,0 1,0,0,a,b,i,c,0,6,0 0,0,0,a,b,i,c,0,6,1 1,0,0,a,b,c,i,d,0,0 0,0,0,a,b,c,i,d,0,1 1,a,b,c,d,e,f,i,g,0 0,a,b,c,d,e,f,i,g,1 1,a,b,c,d,e,f,g,i,0 0,a,b,c,d,e,f,g,i,1 1,i,a,b,c,d,e,f,g,0 0,i,a,b,c,d,e,f,g,1 1,a,i,b,c,d,e,f,g,0 0,a,i,b,c,d,e,f,g,1 1,0,a,i,b,c,d,e,f,0 0,0,a,i,b,c,d,e,f,1 5,a,b,c,d,e,f,g,0,0 7,a,b,c,d,e,f,g,0,1

1. State 2 cell resumes its course and bounces off state 3 ends.

0,6,0,a,i,b,c,d,0,2 0,0,0,3,0,0,0,2,0,2 0,0,0,0,3,0,2,0,0,6 2,6,0,3,0,0,0,0,0,0 0,0,6,2,0,0,0,0,0,2 0,0,0,6,2,0,0,0,0,2 0,0,2,2,a,b,c,0,0,2 0,0,0,2,2,0,0,0,0,2 3,0,0,0,0,0,0,2,6,0 0,3,0,0,0,0,0,0,2,3 6,0,0,0,3,2,0,0,0,0 6,0,0,0,0,0,2,0,0,0 2,2,0,0,a,b,c,0,0,0 2,0,6,0,0,2,0,0,0,0 2,0,0,0,0,2,0,0,0,0 0,0,2,0,0,0,0,0,3,2 2,0,0,0,0,0,0,0,3,0 0,3,0,2,0,0,0,0,0,3 3,0,0,0,2,0,0,0,0,0 0,0,0,0,2,0,3,0,0,2 3,3,0,0,0,0,0,0,l,0 2,0,0,0,0,0,3,0,0,0

1. When a state 6 cell hits the state 3 row at the top, it turns that cell into 1.

0,3,3,0,0,6,0,0,j,6 6,3,3,0,0,0,0,0,j,0 3,a,b,3,0,6,0,j,c,1 0,3,0,0,6,0,0,0,3,2

1. The state 6 cell at the far right makes a state 2 cell, which recreates the state 3 row 1 cell downward.

3,a,b,c,l,2,0,j,d,0 2,j,a,l,0,0,0,0,k,3 0,j,k,2,0,0,0,0,1,2 0,j,k,2,0,0,0,0,3,2 0,3,0,3,0,0,0,0,0,3 3,0,0,0,3,0,0,0,0,0
