The string "1101011010" may be broken up into four parts (1, 10, 101, 1010) that are also the binary representations of a sequence of numbers in increasing order: 1, 2, 5, 10. These numbers are the divisors of 10. Then 858 is in the sequence. %Y A182623 Cf. A007088, A027750, A182620, A182621, A182622, A182624. %K A182623 nonn,base %O A182623 1,2 %A A182623 _Omar E.
