Send the message<br> <p> lookup 1 2 5 14 42 132 429         [no commas!]<br> <p> for example (with no Subject line). Up to 30 sequences can be submitted at the same time. <p> The email reply will tell you any sequences in the OEIS (up to a limit of 50) that match your sequence. <p> If the word "lookup" does not appear in your message, you will be sent the <a href="/helper.txt">help file</a> for this server. <p> You can also retrieve sequences by A-number -- say<br> lookup A12<br> lookup A45<br> lookup A129<br> etc <p> (However, you can't have both sequence lookups and A-number lookups in the same email message.) <p> </li> <p> <li> The second server, <strong>Superseeker</strong>, does not just look up the sequence in the OEIS, it will also apply a large number of algorithms in order to attempt to explain the sequence. Send a message to <p><a href="mailto:superseeker@oeis.org"> superseeker@oeis.org</a> <p>containing a line like <p> lookup 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 <p> (with no Subject line). The program will try VERY hard to find an explanation. Only one request may be submitted at a time, and (since this program does some serious computing), only one request per user per hour please. If there is no lookup line you will receive the <a href="/superhelp.txt">help file</a> for Superseeker. </li> </ul> <p> <div align="center"> <p> <hr> <IMG SRC="celtic_bar.gif" ALT=" "><hr> <p> <h1>Source Code For Email Servers and Superseeker</h1> <p> Click <a href="ol_source.txt">here</a>. </div> <p> <div align="center"> <hr> <IMG SRC="celtic_bar.gif" ALT=" "><hr> <p> </div> <p> </div></div> <p> <div class=footerpad></div> <div class=footer> <center> <div class=bottom> <div class=linksbar> <a href="/">Lookup</a> <a href="/wiki/Welcome"><font color="red">Welcome</font></a> <a href="/wiki/Main_Page"><font color="red">Wiki</font></a> <a href="/wiki/Special:RequestAccount">Register</a> <a href="/play.html">Music</a> <a href="/plot2.html">Plot 2</a> <a href="/demo1.html">Demos</a> <a href="/wiki/Index_to_OEIS">Index</a> <a href="/webcam">WebCam</a> <a href="/Submit.html">Contribute</a> <a href="/eishelp2.html">Format</a> <a href="/wiki/Style_Sheet">Style Sheet</a> <a href="/transforms.html">Transforms</a> <a href="/ol.html">Superseeker</a> <a href="/recent">Recents</a> </div> <div class=linksbar> <a href="/community.html">The OEIS Community</a> </div> <div class=linksbar> Maintained by <a href="http://oeisf.org">The OEIS Foundation Inc.</a> </div> <div class=dbinfo>Last modified November 24 04:30 EST 2024.
