• Numbers k such that the period of the continued fraction for sqrt(k) contains exactly 55 ones.at n=1A031823
• This table shows the coefficients of combinatorial formulas needed for generating the sequential sums of p-th powers of triangular numbers. The p-th row (p>=1) contains a(i,p) for i=1 to 2*p-1, where a(i,p) satisfies Sum_{i=1..n} C(i+1,2)^p = 3 * C(n+2,3) * Sum_{i=1..2*p-1} a(i,p) * C(n-1,i-1)/(i+2).at n=38A087127
• a(n) = 62*n^2 + 1.at n=27A158676
• Number of n X 3 arrays with rows being permutations of 0..2 and no column j greater than column j-1 in all rows.at n=5A212850
• T(n,k) = number of n X k arrays with rows being permutations of 0..k-1 and no column j greater than column j-1 in all rows (n, k >= 1).at n=33A212855
• Number of 6 X n arrays with rows being permutations of 0..n-1 and no column j greater than column j-1 in all rows.at n=3A212859
