OEIS Sequences

a(n) = n2 + (n + 1)3 + (n + 2)4 + (n + 3)5. A61224
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 Qp. Here two algebra extensions are equivalent if they become isomorphic after tensoring with the maximal unramified extension of Qp. A131139
