# A Study of Notation #10  (still rough notes)

## Extending 2 and 5

###### 16,777,216.to.134,217,728

Observation:  The number 10, sometimes understood as 2 times 5, is  the tenth doubling of the Planck numbers; and within this system of numbers, geometries, and formulas,  the question is asked, “What happens within a notation that is divisible by other notations? Does it have any special relation with Notation #2 and #5?”

Planck unit doubles. Is it meaningful to say that 8.27×10-33 meters is nine times larger than the Planck Length?  Does this notation help to stabilize all the different structures that have begun to emerge?  With an abundance of point-free vertices with which to make rather idealized constructions, what could possibly be going on at this juncture.
