[seqfan] Re: a permutation of the naturals

[Andrew Weimholt]

The Catapult Sequence will be A167161
The four related sequences will be A167162 through A167165.
I sent a separate email with b-files attached, but I got an automated

%N A167161 The Catapult Sequence
%C A167161 This sequence is conjectured to be a permutation of the non-negative
%C A167161 integers, generated by the following process:
%C A167161 Begin with the non-negative integers in their normal positions.
%C A167161 Starting with n=0, the number in position n, which will be our a(n),
%C A167161 "catapults" the neighbor to its right a(n) spaces further to the
%C A167161 right. Increment n and repeat.
%C A167161 Whether or not this is actually a permutation of the non-negative
%C A167161 integers depends on whether or not there exists a number that is
%C A167161 catapulted an infinite number of times. If such a number (say X)
%C A167161 exists, the inverse "permutation" will be undefined at the Xth term.
