256/81 (~= 3.16) as the stand-in for π.

Interesting choice, it suggests they didn't have any way to verify the accuracy of that approximation, since 22/7 is way closer, but (4/3)^4 is really cute and elegant.

    Also the volume of the sphere is then (4/3)^5 r^3 so i wonder if it had something to do with trying to unify that
