Line 4:
The '''Yellowstone sequence''', also called the '''Yellowstone permutation''', is defined as:
====a(n) = n for n <= 3. ====
For n >= 4,
====a(n)
The sequence is a permutation of the natural numbers, and gets its name from what its authors felt was a spiking, fountain like appearance of a plot of the sequence.
