A114149 - cp's OEIS frontend

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).
