2.3: Everything Is Something (Solution)

Back to hunt | Back to puzzle set
```Author: David Savitt and Chris Morse

This puzzle is based around the On-Line Encyclopedia of Integer Sequences,
which can be found at http://www.research.att.com/~njas/sequences.
The misspelling of Sloan as Sloane in the flavour text clues Neil Sloane,
the compiler of the encyclopedia.  (More obliquely, the puzzle's title
has acronym EIS, as does the Encyclopdia.  Not that that will help anyone.)
The EIS is fairly well-known among mathy types, so it's reasonable to expect
people to figure this out.

When the solver enters the given sequence into the EIS, they'll find a
message like the following (in addition to a thorough description of the
sequence):  "Congratulations!  You've found the MIT IAP Mystery Hunt
Encyclopedia of Integer Sequences puzzle.  Go to http://whatever for
instructions on finding the next sequence."  (As of writing this solution,
we have not yet finalised the URL.)

At that URL, they see a web page with a form.  They're told to note that
each sequence in the EIS has an identifying A-number, and that they should
enter the A-number from the sequence they just found into the form.
The CGI script waits 90 seconds and then tells them if they're right or
wrong.  If right, they receive a list of trivia questions whose answers
form the next sequence.  After the fifth set of trivia, they're told
that the answer to the puzzle is ASSOCIATION.

Vancouver Canucks NHL team.  There are a few hitches, though.  (First of all,
put all these names into a search engine simultaneously, and up comes a
Each name is associated to a number too.  The reason that a list of Canucks
doesn't come up is that Corey Schwab wasn't acquired until this season, so
he's not on the list.)

Answer after getting the last sequence: ASSOCIATION

One can't use the EIS to search for sequences with gaps; however, note
that one didn't need to solve all the trivia in one set to get to the next
set: once one gets three or four consecutive answers, that's often enough
to cut down the search to under 100 sequences, and from there one can look
