Matrix 3 x 3 in SQL / PL/SQL

Question

Hello All,
I would like a brief help in getting an output like a matrix 3x3. The matrix should be as follow
1 1 1
1 1 1
1 1 1
Imagine that like a table or excel sheet ; i want in each cell like a container from 1 to 5 so , in each cell i can have from 1 to 5 ..
How to get an output in order to print it with all this possible combinations..
I was multiplying the matrix 3 * 3 which would yield 9 and this in turn multiplied by 5 which is the maximum value that each cell can contain. So 9*5 = 45.
but what i want to get is all posible combinations from
1 1 1
1 1 1
1 1 1
to
5 5 5
5 5 5
5 5 5
Thx for your help..

Well, these are the first ten...replace 10 with the number of matrices you want to display:
SQL> with t as (
  2  select 1 c from dual union
  3  select 2 from dual union
  4  select 3 from dual union
  5  select 4 from dual union
  6  select 5 from dual)
  7  select t1.c||' '||t2.c||' '||t3.c||chr(10)||
  8         t4.c||' '||t5.c||' '||t6.c||chr(10)||
  9         t7.c||' '||t8.c||' '||t9.c matrices
10  from t t1, t t2, t t3, t t4, t t5, t t6, t t7, t t8, t t9
11  where rownum<=10;
