%N A continued fraction transformation of e.

%C The terms of the continued fraction representation of this constant (2.126671411...) are the decimal digits of e.

%C When trying to recover the digits of e from this continued fraction, one gets 2, 7, 1, 8, 2, 8, 1, 8, 2, 8, 4, 5, 13, 5, ... whereas e is 2.718281828459045...; recovered "digits" (sometimes greater than 9) that do not match the actual decimal digits of e occur around places where the actual digits include a 0. E.g., the "904" substring in the actual digits of e results in a recovered "digit" of 9+4 = 13. - _Michel Marcus_ and _Jon E. Schoenfield_, Mar 16 2018
