A186329 Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) before g(j) when f(i)=g(j), where f and g are the pentagonal numbers and the hexagonal numbers.  Complement of A186328. 4
2, 4, 6, 8, 10, 12, 14, 17, 19, 21, 23, 25, 27, 30, 32, 34, 36, 38, 40, 42, 45, 47, 49, 51, 53, 55, 58, 60, 62, 64, 66, 68, 70, 73, 75, 77, 79, 81, 83, 86, 88, 90, 92, 94, 96, 98, 101, 103, 105, 107, 109, 111, 114, 116, 118, 120, 122, 124, 127, 129, 131, 133, 135, 137, 139, 142, 144, 146, 148 (list; graph; refs; listen; history; text; internal format)

EXAMPLE

First, write

1..5...12....22.....35......  (pentagonal)

1....6....15....28.......45.. (hexagonal)

Then replace each number by its rank, where ties are settled by ranking the pentagonal number before the hexagonal:

a=(1,3,5,7,9,11,13,15,16,....)=A186328

b=(2,4,6,8,10,12,14,17,19,...)=A186329.
