You may check this by asking for the class name for this integer object

The answer
 LargePositiveInteger



So for example
 26 ** 40
is

      397131118389635994560666234198316439032157304558637285376

The same with a keyword message
 26 raisedTo: 40
      397131118389635994560666234198316439032157304558637285376


Type
   #(3 2 5 65 -1) asSortedCollection
then "print it"


Then "Save and quit". This keeps the UI configuration and maintains the state of opened windows.
