COMMENTS

This sequence uses American English spellings; e.g., 84672 ends in "six hundred seventy-two", not "six hundred and seventy-two" (cf. A006944). Also, for purposes of this sequence, hyphens are treated as spaces, so "seventy-two" is counted as two words ("seventy two"). - Jon E. Schoenfield, Nov 18 2018
