Answer 1

Go to menu Tools → Script Editor...

Paste this code:

function crossJoin(arr1, arr2, delim) {

  delim = delim || '';

  var result = [];
  var row = [];
  for (var i = 0; i < arr1.length; i++) {
    for (var j = 0; j < arr2.length; j++) {
      row = [];
      row.push('' + arr1[0,i] + delim + arr2[0,j]);
      result.push(row);
    }   
  }
  return result;
}

Save project.

Use it as regular function in spreadsheet:

=crossJoin(A1:A132,B1:B52)

Optionaly use delimeter:

=crossJoin(A1:A132,B1:B52, "-")
