Re: [math-fun] An easy August sequence riddle (answer)
Spoiler: https://oeis.org/A275590 --------------
Hello Math-Fun, this is a permutation of the integers from 1 to 35; what are the next two terms?
one, FOUR, two, three, FIVE, NINE, ELEVEN, TWELVE, six, seven, eight, ten, THIRTEEN, FOURTEEN, fifteen, sixteen, seventeen, EIGHTEEN, NINETEEN, TWENTY, twenty-one, twenty-two, twenty-three, TWENTY-FOUR, TWENTY-FIVE, TWENTY-NINE, THIRTY, THIRTY-FOUR, twenty-six, twenty-seven, twenty-eight, thirty-one, thirty-two, thirty-three, THIRTY-FIVE,... Best, É.
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:

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

I did some editing of A275590 to make it a bit clearer. Best regards Neil Neil J. A. Sloane, President, OEIS Foundation. 11 South Adelaide Avenue, Highland Park, NJ 08904, USA.
