• Counts 2-wild partitions. In general p-wild partitions of n are defined so that they are in bijection with geometric equivalence classes of degree n algebra extensions of the p-adic field Q_p. Here two algebra extensions are equivalent if they become isomorphic after tensoring with the maximal unramified extension of Q_p.at n=13A131139
• Numbers up to 10^n with an even number of not necessarily distinct prime factors, or positive Liouville function.at n=5A212818
• Number of length 5+1 0..n arrays with the sum of the cubes of adjacent differences multiplied by some arrangement of +-1 equal to zero.at n=10A250232
• Number of times prime(n) occurs as the least prime factor among numbers 1 .. prime(n)^4: a(n) = A078898(A030514(n)).at n=20A250478
• Number of cells that are a distance of n away in an order-5 hyperbolic square tiling.at n=12A377322
