OEIS Sequences

Octahedral numbers: a(n) = n*(2·n² + 1)/3. A5900

a(n) = (2·n - 1)*(8·n² - 8·n + 3)/3. A63496

Greatest integer k such that k/2ⁿ < (1+sqrt(5))/2 (the golden ratio). A293313

Denominators of continued fraction convergents to sqrt(982). A42901

Partial sums of the odd triangular numbers (A014493). A352116

Numbers k such that the decimal part of k^1/9 starts with a 'nine digits' anagram. A34284

a(n) = k if k is odd otherwise a(n) = k+1 and k = floor( 2ⁿ*(1+sqrt(5))/2 ). A376448

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 k values. A53019
