COMMENT
|
A permutation of positive integers.
|
|
FORMULA
|
Does a(n)=n+o(n)? Does a(n)=n for infinitely many values of n?
|
|
EXAMPLE
|
Runs of odd or even terms are : (1),(2,4),(3,5,7,9),(6,8,10),(11,13,15,17,19),...and computing the number of integers in each run we get : 1,2,4,3,5,...the sequence itself.
