COMMENTS

By "reversal" of k's representation in binary, it is meant: write k in binary, reverse the order of its digits, and read the result as a binary value.

This sequence contains all the even positive integers.

LINKS

Table of n, a(n) for n=1..69.

EXAMPLE

29 in binary is 11101. Its digital reversal is 10111, which is 23 in decimal. Since 29 > 23, 29 is in this sequence.
