0 n% q6 c! Q' q, n
So the right hand side number 0 can be represented by number 1 公仔箱論壇2 P# r/ B& n( X
The right hand side number 1 can be represented by 3,1,2,9,7,52 ~& e4 f6 h' ^1 p; k7 I; X1 P$ i/ w5 ~
The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0% ]0 w8 @1 x& J; o, D
The right hand side number 3 can be represented by 5,9,8,37 O7 Z( ]1 W, w. u4 m( i# I0 H
The right hand side number 4 can be represented by 65.39.217.77:8898: h( s7 {, m" r7 c) G
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2公仔箱論壇3 U' f: q. w$ c
