Do you mean something like this?

Code:

awk 'BEGIN {
  for (x = 0; ++x <= 10;) 
    for (y = 0; ++y <= 5;)
      aOa[x][y] = "element:" FS x FS y
    
  for (i in aOa)
    for (j in aOa[i])
      print aOa[i][j]
  }'

Code:

% awk 'BEGIN {
  for (x = 0; ++x <= 10;)
    for (y = 0; ++y <= 5;)
  aOa[x][y] = "element:" FS x FS y

  for (i in aOa)
    for (j in aOa[i])
      print aOa[i][j]
  }'
element: 4 4
element: 4 5
element: 4 1
element: 4 2
element: 4 3
element: 5 4
element: 5 5
element: 5 1
element: 5 2
element: 5 3
element: 6 4
element: 6 5
element: 6 1
element: 6 2
element: 6 3
element: 7 4
element: 7 5
element: 7 1
element: 7 2
element: 7 3
element: 8 4
element: 8 5
element: 8 1
element: 8 2
element: 8 3
element: 9 4
element: 9 5
element: 9 1
element: 9 2
element: 9 3
element: 10 4
element: 10 5
element: 10 1
element: 10 2
element: 10 3
element: 1 4
element: 1 5
element: 1 1
element: 1 2
element: 1 3
element: 2 4
element: 2 5
element: 2 1
element: 2 2
element: 2 3
element: 3 4
element: 3 5
element: 3 1
element: 3 2
element: 3 3

This is with GNU awk 4.
