%N Alphabetically first list of self-describing statements about the letter-type content of the list itself

%C To decode the sequence, start by replacing the last two digits of a term by a letter of the English alphabet (01=A, 02=B, 03=C, 04=D, ... 26=Z); one gets for the first 11 terms 1A,1B,4O,5O,5E,5F,8E,5V,1C,4N,8F,... Now replace the remaining numbers by their English name: ONE A, ONE B, FOUR O, FIVE O, FIVE E, FIVE F, EIGHT E, FIVE V, ONE C, FOUR N, EIGHT F,... This succession of words is the alphabetically first one describing, step by step, the true state of the list so far.

%C In the first 100000 terms of ONE A, ONE B, FOUR O,..., no term ever starts with T and only one term (#13886) starts with S: SIXTY-FIVE THOUSAND TWENTY-SEVEN E. - _Hans Havermann_, Apr 14 2016

%D This sequence was mentioned for the first time on the math-fun forum on April 10th.

%H Hans Havermann, <a href="http://chesswanks.com/num/AngeliniAlphabet.txt">Table of 1 A, 1 B, 4 O,... for a very large number of terms</a>

%Y This is the equivalent (in English) of A102850.
