Why did this game draw?

It says that was for triple repetition, but I don't see a repeat of three moves in that game. Can anyone explain this tome?

More of a short poem than a tome...

But the position is identical after White's 40th, 42nd and 44th move. That's threefold repetition.

(Repetition is not about moves, it's about position, and the moves do not have to be consecutive.)

Thanks for explaining. I was thinking that ust can have a triple repetition
if it were the moves followed.
