The length is the quantity of letters in a word: "one" is 3-letter long --> odd length FOUR is 4-letter long --> even length The "blocks" are homogeneous as the odd-length words or even-length words come in chunks I've to admit that the process of writing the definition in sound English has taken me quite a while. And is a failure, I'm afraid... If you have a good definition, (even if it is several lines long) don't hesitate to send it to me in private

Best, É. -----Message d'origine----- De : math-fun [mailto:math-fun-bounces@mailman.xmission.com] De la part de Jeffrey Shallit Envoyé : jeudi 4 août 2016 12:24 À : math-fun@mailman.xmission.com Objet : Re: [math-fun] An easy August sequence riddle (answer) I have to admit that, even after reading it several times, I do not understand the description of the sequence given in A275590. What does "odd-length terms of the sequence" mean? What is a length of a sequence element? What does "homogeneous blocks" mean? On 8/4/16 12:08 PM, Eric Angelini wrote:
