EN

  function temp3() {
var ss = 
SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet6");
 var range = ss.getRange("b14:av14");
 var m = 0

 var picks = [];

 for(var j = 1; j < 48; j++) {
  var array1 = [1+m, 2+m, 3+m, 4+m, 5+m, 6+m, 7+m, 8+m, 9+m, 10+m, 
11+m, 12+m, 13+m, 14+m, 15+m, 16+m, 17+m, 18+m, 19+m, 20+m];

  shuffleArray(array1); 
  picks.push(array1[0]);

  m = m + 1
 }
   ss.getRange(16, 2, 1, 47).setValues([picks]); 
}
