Hello SeqFans, Is this the longest possible (English) such chain? No integer shares a letter with its neighbours: EIGHT, FOUR, ELEVEN, TWO, SEVEN, THIRTY, ONE, SIX, ZERO, FIFTY, ONE HUNDRED, FIFTY-SIX, ONE HUNDRED (AND) ONE. ... 13 words. (I have 25 in French, hope this is not old hat again) Best, É.
