Historical sequences

From OeisWiki

Jump to: navigation, search

This is a project for finding historical sequences, locating early references, and for antedating existing sequences. Finding early works and their translations, and making them available on the OEIS, is also included.

The primary focus is on sequences or constants referenced explicitly, though sometimes implicit references to sequences are useful as well.



The main interest is in finding less-well-known references, but this table covers many well-known sequences. Of course even these sequences often lack references to their antiquity; please add information where available!

Ideas for new sequences

  • Quipu are known to record sequences of natural numbers. Are any particular examples notable enough for inclusion? Presumably most contained non-mathematical information, but then again A100000 presumably did as well.

Antedating sequences

Finding earlier references to existing sequences is always useful, even if the sequence is not actually historical.

Finding references

Original sources can be hard to come by. Some old books (or reprints) can be found on Google Books or the arXiv: see for example Euler on the arXiv. JSTOR and other archiving services have some articles back to the 16th century.

  • Costantino Sigismondi, Gerbert of Aurillac: astronomy and geometry in tenth century Europe, arXiv:1201.6094.
  • I was not able to find any integer sequences in Suàn shù shū (Writings on Reckoning)
