(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A278060 Relative of Hofstadter Q-sequence: a(n) = n for 1 <= n <= 8; a(n) = a(n-a(n-1)) + a(n-a(n-2)) for n > 8. 11
1, 2, 3, 4, 5, 6, 7, 8, 3, 9, 10, 5, 11, 6, 7, 12, 14, 10, 8, 14, 18, 12, 15, 8, 23, 13, 10, 17, 13, 25, 16, 19, 20, 13, 19, 29, 18, 17, 30, 24, 24, 20, 23, 26, 20, 27, 24, 26, 38, 13, 28, 38, 30, 20, 42, 35, 19, 45, 30, 32, 29, 45, 23, 32, 40 (list; graph; refs; listen; history; text; internal format)

REFERENCES

Similar to Hofstadter's Q-sequence A005185 but with different starting values.

This sequence has exactly 420 terms, since a(420)=430 and computing a(421) would refer to a(-9).
