Antti Karttunen, Table of n, a(n) for n = 1..65537
EXAMPLE
From 9 one can reach with the transitions x -> A171462(x) (leftward arrow) and x -> A335876(x) (rightward arrow) the following six numbers, when one doesn't expand any power of 2 further:
9
/ \
6 12
/ \ / \
4 8 16
thus a(9) = 6.
From 10 one can reach with the transitions x -> A171462(x) and x -> A335876(x) the following for numbers, when one doesn't expand any power of 2 further:
10
|\
| \
| 12
| /\
|/ \
8 16
thus a(10) = 4.
From 15 one can reach with the transitions x -> A171462(x) and x -> A335876(x) the following seven numbers, when one doesn't expand any power of 2 further:
15
/ \
/ \
12<----18
/ \ \
/ \ \
8 16<----24
\
\
32
thus a(15) = 7.
