See the comment at A075158.

Table of n, a(n) for n=1..61.

Index entries for sequences that are permutations of the natural numbers

a(9) = 7 = 1+6 (1 + 110) as 9 = 3^2 * 2^(1-1). (The run lengths of 6, 110 in binary are 2 and 1).

Inverse of A075159. a(n) = A075158(n-1)+1.

Sequence in context: A263268 A257472 A064787 * A119755 A206710 A175502

Adjacent sequences: A075157 A075158 A075159 * A075161 A075162 A075163
