COMMENT
|
a(n) <= A075421(n); a(n) = A075421(n) iff the trajectory of A075421(n) does not join the trajectory of any smaller number, i.e. A075421(n) is also a term of A091675.
a(n) determines a 1-1-mapping from the terms of A075421 to the terms of A091675. For the inverse mapping cf. A091677.
Base 4 analogue of A089493.

EXAMPLE
|
A075421(1) = 290, the trajectory of 290 (A075299) joins the trajectory of 266 = A091675(12) at 4195, so a(1) = 266. A075421(6) = 1210, the trajectory of 1210 joins the trajectory of 269 = A091675(13) at 17975, so a(6) = 269.
