Properties

Appears in sequences

• Numbers k such that the continued fraction for sqrt(k) has odd period and if the last term of the periodic part is deleted the two central terms are both 41.at n=7A031629
• Primes p such that A001414(p-1) = A001414(p+1), where A001414 = sum of primes dividing n (with repetition).at n=11A086711
• Let [n] = {1,2,...,n}. Let G_n be the union of all closed line segments joining any two elements of [n] X [n] along a vertical or horizontal line, or along a line with slope +-1. Then a(n) = combined total of the number of (nondegenerate) triangles and rectangles for which all edges are subsets of G_n.at n=17A098921
• Primes whose base-6 representation also is the base-3 representation of a prime.at n=41A235469
• Prime numbersat n=9166
