Sorry I did not add this to the previous posting on the Sierpinski triangle but that posting appears to be locked.
I am not sure what counts as an iteration but I think this file is capable of creating 8 iterations. I'll let you be the judge of that. Be aware that on my computer, iteration 6 to 7 took about 20 seconds and iteration 7 to 8 took about 2 minutes. On attempting iteration 9 my computer crashed.
I have used a different approach, from that demonstrated in the earlier post, to create each iteration. I used some buttons with scripting that employs execute and sequence commands.
