There is now a second program to identify sequences. This one will not just look up the sequence in the Encyclopedia, it will also try a large number of tricks in order to attempt to explain the sequence. Send a message to


containing 1 line like

lookup 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37

Start at the beginning, give lots of terms. Minus signs are OK. The program will try VERY hard to find an explanation. There are probably still many bugs, since the program is complicated, - please let me know if you find any. I have made extensive use of programs of Bruno Salvy and Simon Plouffe.

Only one request may be submitted at a time, and (since this program does some serious computing), only one request per user per hour. If there is no lookup line you will get the help file.
