• 6-almost primes with semiprime digits (digits 4, 6, 9 only).at n=16A111730
• a(1)=1, a(n)=a(n-1)+n^1 if n odd, a(n)=a(n-1)+ n^3 if n is even.at n=26A140145
• Numbers k such that there are 10 digits in k^2 and for each factor f of 10 (1, 2, 5) the sum of digit groupings of size f is a square.at n=30A153748
• Number of strings of numbers x(i=1..6) in 0..n with sum i^3*x(i) equal to 216*n.at n=25A184261
• Starting at n, a(n) is the total number of moves made to the right according to the following rules. On the k-th step (k=1,2,3,...) move a distance of k in the direction of zero. If the number landed on has been landed on before, move a distance of k away from zero instead.at n=20A324660
