OEIS Sequences

Let Do(n) = A006566(n) = n-th dodecahedral number. Consider all integer triples (i,j,k), j >= k>0, with Do(i) = Do(j) + Do(k), ordered by increasing i; sequence gives i values. A53017

φ(n) + n is a cube. A114074

Up-down permutations on [n] whose peaks have k rises. A194354

Triangle read by rows: T(n,k) is the number of down-up permutations on [n] whose peaks have k rises. A194365

a(n) = (1/5)*s(n), where s(n) is the n-th multiple of 5 in A026166. A26204
