Mistaken labyrinth notation, where I replaced a 3 with a 5, making 1165.

Spoiler:

7 by 6 with seven unused dots, not optimal - EDIT: WRONG - this is 1165.

¹Notes on this version of p-notation I've been developing

Spoiler:

It occurs to me that I've been using this notation for a while, and haven't really defined it anywhere (I think.). s, p, d, f, g, etc., are prefix binary functions (p*q, p*q^th prime, etc.) and S, P, D, F, G, etc., are constants. (1 = "", 2 = <>, 3 = <<>>, 5 = <<<>>>, 11 = <<<<>>>>, etc..) This way, we can have a nonambiguous grammar without parentheses.

Of course, if I put parentheses afterwards, then the function just applies to the value in front, so s(Number) evaluates to Number, p(Number) evaluates to Number^th prime, etc.; also, in this case, assume sequences of terms evaluate to the product.

Without s, S, or parentheses, we can represent any prime with recursively no more than two factors. With parentheses, or with s, we can represent any number (where 1 is represented by the empty string).

*sigh* We all want to have 709 don't we?

I just realized that 709 is a special number. That explains why the activity suddenly dropped.
