Start with 0, then 0,1; then 2,0 and 1,1; etc. Writing pairs vertically, the initial segments are 0..0..0 1..0 1 2..0 1 2 3..0 1 2 3 4 5..0 1 2 3 4 5 6..0 1 2 3 4 5 6 9 ...1..2 1..3 3 1..4 5 2 2..5 6 5 3 1 1..6 9 6 5 2 4 1..7 11 8 6 4 6 3 1 The 5th segment tells that 0 has been written 4 times, 1 5 times, 2 2 times, and 3 2 times. The nouns are 1 2 3; the adjectives, 5 2 2. - _Clark Kimberling_, Mar 25 2013
