COMMENTS

This real number in base 3/2 is given on p. 3 of Morgenbesser. It is analogous to the base 10/1 Champernowne's constant.

Write 1, 2, 3, 4, 5, 6, ... in base 3/2 to obtain 2, 21, 210, 212, 2101, 2120, 2122, ... and concatenate their digits. [Typo corrected by Eric M. Schmidt, Feb 26 2015]

The base 3/2 representation of n in the sense of Morgenbesser is given by A024629(2*n). - Eric M. Schmidt, Feb 26 2015
