 Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 59th year, we have over 358,000 sequences, and we’ve crossed 10,300 citations (which often say “discovered thanks to the OEIS”). Other ways to Give

 OFFSET 0,2 LINKS EXAMPLE "1" is in the sequence because if you replace each letter of "one" by its rank in the alphabet you get the string 15145 which contains at least a "1". ["3" produces the string 2081855 which contains no "3" -- thus "3" is not a "self-ranked number".] CROSSREFS Sequence in context: A174438 A176061 A183234 * A289628 A047387 A063282 Adjacent sequences: A108965 A108966 A108967 * A108969 A108970 A108971 KEYWORD base,easy,nonn,word AUTHOR Eric Angelini, Jul 26 2005 EXTENSIONS More terms from Sean A.
