The OEIS Foundation is supported by donations from users of the OEIS and by a grant from the Simons Foundation.



Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

Transformations of Integer Sequences

A subpage of the The On-Line Encyclopedia of Integer Sequences, which makes extensive use of these transformations.

 Keywords: AND-convolution, BINOMIAL transform, BINOMIALi transform, BISECT, boustrophedon transform, characteristic function, complement of sequence, compose two sequences, functional square root, continuant transform, convolution transform, inverse convolution transform, decimate, first differences, DIGREV = reverse digits, DIGSUM = sum of digits, Dirichlet convolution, Euler transform, Euleri transform, exponential transform, exponential convolution, GCD-convolution, Hankel transform, inverse of permutation, INVERT transform, INVERTi transform, LAH transform, LAHi transform, Lambert function, LCM-convolution, little Hankel transform. logarithmic transform, MOEBIUS transform, MOBIUS transform, MOEBIUSi transform, MOBIUSi transform, OR-convolution, partial products, partial sums, PARTITION transform, PARTITIONi transform, RECORDS transform, revert (or reversion), REVEGF = reversion of e.g.f., SERIESTOLISTDIV, SERIESTOLISTMULT, SERIESTOSERIESDIV, SERIESTOSERIESMULT, SERIES2, SERIES2TOLIST, SERIES2TOLISTMULT, SERIES2HTOLIST, SERIES2HTOLISTMULT, sort, STIRLING transform, STIRLINGi transform, Stirling-Bernoulli transform, SUPPORT transform, trisect, XOR-convolution, WEIGH transform, Maple, Mathematica, PARI.

This page has links to four other web pages which give procedures for performing a large number of useful transformations on sequences and numbers. The programs

  • Maple programs.
  • Mathematica programs, written by Olivier Gerard.

  • PARI programs, written by Christian G. Bower.
  • See also the description of some further transforms written by Christian G. Bower.
