What's the next whole number in this sequence: 2, 4, 7, 11, 16, 22, 29?

The answer can be found in one of more than 5,000 entries in the Encyclopedia of Integer Sequences (Academic Press, 1995), a unique mathematical catalog compiled by Neil J.A. Sloane of AT&T Bell Laboratories in Murray Hill Murray Hill may refer to one of the following places:
  • Murray Hill, Kentucky
  • Murray Hill, Manhattan, a residential neighborhood in New York City
  • Murray Hill, Queens, a different locality in New York City
  • Murray Hill, New Jersey
  • Murray Hill, Pennsylvania
, N.J., and Simon Plouffe Simon Plouffe is a Quebec mathematician born on June 11 1956 in , Quebec. He discovered the formula for the BBP algorithm (the Bailey-Borwein-Plouffe formula) which permits the computation of the nth binary digit of π, in 1995.  of the University of Quebec in Montreal.

Starting with "the zero sequence," which consists of an infinite string of zeros, each entry in this catalog gives the first dozen or more numbers of a particular sequence, the sequence's name, a mathematical description or formula showing how to obtain successive terms, and citations indicating where the sequence has come up in the mathematical or scientific literature.

Sloane has been collecting integer sequences since 1965, when he was a graduate student at Cornell University Cornell University, mainly at Ithaca, N.Y.; with land-grant, state, and private support; coeducational; chartered 1865, opened 1868. It was named for Ezra Cornell, who donated $500,000 and a tract of land. With the help of state senator Andrew D. . Within a decade, he had enough material to publish an annotated list of 2,372 sequences in A Handbook of Integer Sequences (Academic Press, 1973). This volume became a standard reference for mathematicians and many others interested in numbers in a wide variety of contexts, from studies of knots to research on RNA RNA: see nucleic acid.

Sloane also has an on-line version of his new sequence encyclopedia. By sending a message such as "lookup 5 14 42 132" to the electronic mail address (messaging) electronic mail address - (Usually "e-mail address") The string used to specify the source or destination of an electronic mail message. E.g. "john@doc.acme.ac.uk".

The RFC 822 standard is probably the most widely used on the Internet. X.

Since completing the encyclopedia, Sloane has added more than 500 new sequences to his collection. About 250 of these entries have come from R.G.Kunstleve, a crystallographer crys·tal·log·ra·phy
