A358668 a(n) is the least m such that A359194^k(m) = n for some k >= 0 (where A359194^k denotes the k-th iterate of A359194). 2

%N a(n) is the least m such that A359194^k(m) = n for some k >= 0 (where A359194^k denotes the k-th iterate of A359194).

%C See A359214 for the corresponding minimal k's.

%F a(n) <= n.

%e The orbit of 0 under repeated application of A359194 is:

%e 0, 1, 0, ...

%e So a(0) = a(1) = 0.

%e The orbit of 2 under repeated application of A359194 is:

%e 2, 1, 0, 1, 0, ...

%e So a(2) = 2.

%e The orbit of 3 under repeated application of A359194 is:

%e 3, 6, 13, 24, 55, 90, 241, 300, 123, 142, 85, 0, 1, 0, ...

%e So a(3) = a(6) = a(13) = a(24) = a(55) = a(90) = a(241) = a(300) = a(123) = a(142) = a(85) = 3.
