Appears in sequences
- Operation count to create all permutations of n distinct elements using the "streamlined" version of Algorithm L (lexicographic permutation generation) from Knuth's The Art of Computer Programming, Vol. 4, chapter 7.2.1.2. Sequence gives number of comparisons required to find j in step L2.2'.at n=7A079750
- Square numbers which are the sum of distinct double factorials (A006882).at n=35A115648
- Triangle read by rows: T(i,j) for the recurrence T(i,j) = (T(i-1,j) + 1)*i.at n=48A121662
- Triangle read by rows: T(m,n) = Sum_{i=1..n} P(m,i) where P(m,n) = m!/(m-n)! is the number of permutations of m items taken n at a time, for 1 <= n <= m.at n=51A285268
