Hello Math-Fun, We want to build a column of true statements; every step makes a true statement about the count of the letters involved so far in the column. Example of such a column: TWO T THREE E THREE H FOUR R ... Explanation: At stage 1 the column is made of this true statement about the column itself: "There are 2 T's so far in C" ("C" is short for "column") At stage 2 the column is made of this true statement about the column itself: "There are 3 E's so far in C" At stage 3 the column is made of this true statement about the column itself: "There are 3 H's so far in C" At stage 4 the column is made of this true statement about the column itself: "There are 4 R's so far in C" etc. There are lots of such "self-columns", but we want here the alphabetically first one. It will start, I guess, like this: ONE A ONE B FOUR O FIVE O FIVE E EIGHT E etc. Question: when will this column end? Best, É. à+ É. Catapulté de mon aPhone
