 A278064 Relative of Hofstadter Q-sequence: a(n) = n for 1 <= n <= 12; a(n) = a(n-a(n-1)) + a(n-a(n-2)) for n > 12. 11

 OFFSET 1,2 COMMENTS Similar to Hofstadter's Q-sequence A005185 but with different starting values. This sequence has exactly 69 terms, since a(69)=77 and computing a(70) would refer to a(-7).
