• Unsigned Stirling numbers of first kind s(n,5).at n=5A000482
• Expansion of Product_{k>=1} (1 - x^k)^15.at n=41A010822
• Number of partitions of n into parts of 18 kinds.at n=6A023016
• Triangle read by rows: T(n,k) = |s(n,n+1-k)|, where s(n,k) are the signed Stirling numbers of the first kind A008276 (1 <= k <= n; in other words, the unsigned Stirling numbers of the first kind in reverse order).at n=50A094638
• Alfred Moessner's factorial triangle.at n=40A125714
• Triangle T(n,k), 0 <= k <= n, read by rows, giving coefficients of the polynomial (x+1)(x+2)...(x+n), expanded in increasing powers of x. T(n,k) is also the unsigned Stirling number |s(n+1, k+1)|, denoting the number of permutations on n+1 elements that contain exactly k+1 cycles.at n=49A130534
• Triangle of unsigned Stirling numbers of the first kind (see A048994), read by rows, T(n,k) for 0 <= k <= n.at n=60A132393
• (Signless) Central Stirling numbers of the first kind s(2n,n).at n=5A187646
• Numbers n with the property that if the base-8 representation of n is read backwards, the result is 5*n.at n=4A217742
• Numbers k with the property that if the base-8 representation of k is read backwards, the result is an integral multiple of k.at n=20A223090
• Triangle read by rows. T(n, k) = |Stirling1(k + n, n)|.at n=20A354979
