A saw tooth, but each partial is a saw tooth and so on, each saw tooth has 8 partials. I did 5 layers of this, Pd's clone object breaks on the 5th layer. I also tried increasing the number of partials in each layers, but Pd also breaks.
On the main file you will encouter:
osc - 1 partial
saw tooth - 8 ^ 1 partials
sawsaw tooth - 8 ^ 2 partials
sawsawsaw tooth - 8 ^ 3 partials
sawsawsawsaw tooth - 8 ^ 4 partials
sawsawsawsawsaw tooth is in the main-osc-layer5 file and doesn't play correctly
