HELP FILE FOR EMAIL SERVICE THAT AUTOMATICALLY LOOKS UP A SEQUENCE
*********************************************************************
Greetings from
The On-Line Encyclopedia of Integer Sequences
(http://oeis.org)
Maintained by The OEIS Foundation Inc. Please donate!

INSTRUCTIONS:
To look up a sequence in the OEIS, send email to
sequen...@oeis.org
containing a line of the form
lookup 4 9 16 25 36
for each sequence (up to a limit of 30) that you would like looked up.
Put these lines in the body of the message. As Subject line, say "None".
The reply will report all sequences found in the OEIS
(up to a limit of 50) that match your sequence.
Alternatively, you can say
lookup A41
lookup A000112
etc.
(up to a limit of 30)
if you know the A-numbers of the sequences you are want to see.
(However, you cannot mix the two kinds of lookups.)
RECOMMENDATIONS:
. If you receive 50 matches, try again giving more terms
. Minus signs should generally be omitted, since people
may have different opinions about the choice of signs
. For a sequence of rational numbers, try the numerators
and denominators separately
. For an array of numbers, either:
(i) try looking up the individual
rows, columns or diagonals, whichever seem appropriate,, or
(ii) convert the array into a sequence by reading it
across rows or columns (for example, Pascal's triangle
gives 1,1,1,1,2,1,1,3,3,1,1,4,6,4,1 etc.)
. It is best to leave out the first term or two, since
there may be several ways to begin the sequence
. Give as many terms as possible (although if you give
more terms than are in the table, the program will
not find a match - so don't give TOO many!)
COMMON ERRORS WHEN USING THIS EMAIL SERVICE:
Make sure that
the word "lookup" does not appear in the message in the same line as
any non-numeric characters. Make sure that the lookup line
has the form
lookup 1 4 9 16 25 GOOD!
and avoid any lines that say things like:
Subject: lookup please BAD!
Subject: lookup BAD!
To: lookup <sequen...@oeis.org> BAD!
lookup 1,4,9,16,... [NO COMMAS OR DOTS ARE ALLOWED!] BAD!
lookup 1 4 9 16 ? BAD!
lookup BAD!
In a submission to superseeker the word "lookup" may only
appear once in the entire message.
