 A231116 Numbers n such that the total number of digits of all the divisors of n written in base 2 is equal to n. 0
 1, 3, 10, 24 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,2 COMMENTS Sequence is finite with 4 terms. Numbers n such that the concatenation of their divisors written in base 2 contains n digits. Subsequence of finite sequence: 1, 2, 3, 4, 6, 8, 10, 12, 24 (numbers n such that the total number of digits of all the divisors of n written in base 2 is greater than or equal to n). Numbers n such that A182627(n) = n. LINKS Table of n, a(n) for n=1..4. EXAMPLE 24 is in the sequence because the concatenation of the divisors of 24 in base 2 [(1, 10, 11, 100, 110, 1000, 1100, 11000) -> 110111001101000110011000] contains 24 digits. CROSSREFS Cf. A182622, A182627. Sequence in context: A105861 A228493 A041327 * A272953 A259443 A293405 Adjacent sequences: A231113 A231114 A231115 * A231117 A231118 A231119 KEYWORD nonn,base,fini,full,less AUTHOR Jaroslav Krizek, Nov 03 2013 STATUS approved
