• Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 36.at n=34A031714
• a(n) = 1225*n^2 + 35.at n=18A158733
• Triangle read by rows: T(n,k) is the number of permutations of {1,2,...,n} having k nonincreasing cycles (0<=k<=floor(n/3)). A cycle (b(1), b(2), ...) is said to be increasing if, when written with its smallest element in the first position, it satisfies b(1) < b(2) < b(3) < ... .at n=29A186756
