A114149 Self-describing sequence: 1 even integer between two odd, then 2 even integers between two odd, then 3 even integers, then 4, then 6... The length of each run of even integers is given by the sequence itself (the smallest odd available integer is used when needed).

1, 2, 3, 4, 6, 7, 8, 10, 12, 13, 14, 16, 18, 20, 21, 22, 24, 26, 28, 30, 32, 33, 34, 36, 38, 40, 42, 44, 46, 47, 48, 50, 52, 54, 56, 58, 60, 62, 63, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 83, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 107, 108, 110, 112, 114, 116, 118

Examples

			Runs of even integers are between brackets:
1,(2),3,(4,6),7,(8,10,12),13,(14,16,18,20),21,(22,24,26,28,30,32),33...
1 even 2 even 3 even 4 even 6 even... etc. = the sequence itself
