COMMENTS

If symmetry is not taken into account, these numbers are approximately 8 times larger (except for those at the start). The sum of this (finite) sequence is 23475688, the total number of distinct board positions that can be reached from the central vacancy on the 33-hole peg solitaire board.

EXAMPLE

There are four possible first jumps, but they all lead to the same board position (rotationally equivalent), thus a(1)=1.
