 OFFSET 1,3 COMMENTS Conjectured convergent of a(n)/a(n-1) = phi^2, 2.6180339... a(19)/a(18) = 10310703/3938272 = 2.6180779.... LINKS FORMULA Let M = triangle A168316 as an infinite lower triangular matrix. Shift M down one row, inserting a "1" at top. A168317 = Lim_{n->inf.} M^2, the left shifted vector considered as a sequence. CROSSREFS Cf.
