COMMENTS

To decode the sequence, start by replacing the last two digits of a term by a letter of the alphabet (01=A, 02=B, 03=C, 04=D, ... 26=Z); one gets for the first 11 terms 2D, 3D, 2I, 5D, 5I, 2O, 2R, 5E, 5C, 5U, 5X,... Now replace the remaining numbers by their French name: DEUX  D, TROIS  D, DEUX  I, CINQ  D, CINQ  I, DEUX  O, DEUX  R, CINQ  E, CINQ  C, CINQ  U, CINQ  X,... This succession of words is the alphabetically first one describing, step by step, the true state of the list so far.
