TWENTY-SEVEN has eleven letters, ELEVEN has six letters, SIX has three letters, THREE has five letters, and FIVE has four letters. No matter what number name one starts with, one always ends up at FOUR. Suppose instead one adds the number of letters in the name to the number itself to obtain a new number-name: TWENTY-SEVEN with eleven letters goes to THIRTY-EIGHT, and this sequence continues with FORTY-NINE, FIFTY-EIGHT,... ending with one of the last eight hundred number names in the thousand vigintillions.
