Hello everyone. I have been trying to solve a pi clock which is attach. I figured out most of the positioins except the 5 and 7 positions. 5 = RANK([pi,((S**1)**5)) 7 = pi, L(7,3) On the 5 position, I am guessing S is a sum series. I am not sure if the power is a 1. As for the 7 position, I think the L is a Eulidean norm vector.

I used the IMG tags to display the larger image, and then removed the now unnecessary link to the image.

For the fifth position, I think that is the first homotopy group of the sphere. No idea about the seventh position, though.

I found the solution to the other question pertaining to 7 = pi (sub 1), (L(7,3)). The L in here is the least common denominator which is 21. The pi (sub 1) of (21) is the number of prime numbers except the first one from 1 to 21 which is 7.

It was meant as a suggestion for your nice clock.
