• Number of immersions of oriented circle into oriented sphere with n double points.at n=8A008986
• Numbers n such that 49*2^n-1 is prime.at n=28A050550
• Balanced primes of order nine.at n=34A096701
• Triangle read by rows: T(n,k) is the number of permutations of {1,2,...,n} having k increasing cycles (0<=k<=n). 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=48A186754
• Triangle read by rows: T(n,g) = number of general immersions of a circle with n crossings in a surface of arbitrary genus g, in the case that the circle is oriented and the surface is oriented.at n=28A260285
