Extracting Palindromes from Pi
(e.g. 7446447 & 110000011)
A puzzle/question by Klaas Craye _(†)

Did you know that with the first 14 numbers from Pi
the palindrome 7446447 can be formed.

3 , 1415926 5358979 323...

5358979 – 1415926 = 3943053

now reverse the two numbers of the left side
of the above expression and recalculate :

9798535 – 6295141 = 3503394

3943053 and 3503394
both contain the same digits but are in a different order.

Adding both numbers together gives us our first palindrome !
3943053 + 3503394 = 7446447

Divide a circle in 7
360 / 7 = 51,428571...

XY axes
distance to (0,0) : 7,4,4,6,4,4,7
results in an oval-shape

My puzzle/question :
There are more couples of numbers like these to find in Pi.
Somewhere there is the result 110000011...
