// TestCode.java
public class TestCode {
    public static void main(String args[])
    {
        for(int i = 1;i<=5;i+=2){
            int n = i;
            for(int j = 1;j<27;j++){
                if(j%9==0){
                    System.out.print(n+"#");
                    n = 0;
                }
                else{
                    System.out.print(n+",");
                }
                n += i;
            }
            System.out.println(9*i+"#");
        }
    }
