 Annual Appeal: Please make a donation to keep the OEIS running. In 2018 we replaced the server with a faster one, added 20000 new sequences, and reached 7000 citations (often saying "discovered thanks to the OEIS"). Other ways to donate

 OFFSET 1,2 COMMENTS When the numbers denote finite permutations (as row numbers of A055089) these are the circular shifts to the left within an interval. The subsequence A007489 then denotes the circular shifts that start with the first element. Compare A051683 for circular shifts to the right. - Tilman Piesk, Apr 29 2017 LINKS Tilman Piesk, Table of n, a(n) for n = 1..2016 Tilman Piesk, Circular shifts to the left (Arrays of permutations) EXAMPLE T(3,2) = Sum( 2 <= i <= 4 ) i! = 2! + 3! + 4! = 32.
