Peg Solitaire is mostly known to me as the triangular board with 15 holes and 14 pegs (mostly because of the restaurant Cracker Barrel). The rules are simple: pegs jump each other in straight lines, removing the jumped peg and leaving an additional space each move.
The usual end goal is to remove all but one peg, but that's boring. Instead, I'd like to know how many pegs you can end with, while no longer having a move to make. You may start with any space being the open spot.

O X X X X X X X X X X X X X X
