• Arithmetic progressions of at least 4 terms with common difference 6 having the same value of phi(x) start at these numbers.at n=24A050498
• Let Oc(n) = A005900(n) = n-th octahedral number. Consider all integer triples (i,j,k), j >= k > 0, with Oc(i) = Oc(j)+Oc(k), ordered by increasing i; sequence gives k values.at n=17A053678
