 OFFSET 1,2 COMMENTS Method A = 'frequency' (in binary mode) followed by 'digit'-indication. The number of digits of a(n) is A001609(n) except for n = 2. See the link from T. Sillke below. - Jianing Song, Mar 16 2019 LINKS Kade Robertson, Table of n, a(n) for n = 1..18 Kade Robertson, Table of n, a(n) for n = 1..31 T. Sillke, The binary form of Conway's sequence FORMULA a(n) = A001391(n-1), n > 1. - R. J. Mathar, Oct 15 2008 EXAMPLE E.g., the term after 11110 is obtained by saying "four (i.e., 100 in binary mode) 1, one 0", which gives 100110. CROSSREFS Cf. A001387 (initial term is 1), A001391, A001609 (number of digits), A259710 (written in decimal).
