Reference : https://en.wikipedia.org/wiki/Pi Can we write a Computer program which will print Reverse Digits of Pi series? Final output of the program will be 5,1,4,1,3 Can we start from $\omega$ till 1 for the program? The programming language could be LOLCODE, Befunge, Whitespace, Ook!, Malbolge, etc. Can we name this new Mathematical series as Reverse pi number series? Thanks & Regards

I've been waiting for a chance to use Malbolge! Thank you!

First find the nth digit of pi and reverse it but pi is irrational.

Perhaps a proof using Poe's law could work here.

I think he is asking to show the decimal digits of pi in reverse way but in a bounded way . This can be done with a specific software or simple algorithms . Approximations of pi can be used too . If not then make a statement : Given natural number n , find the function $\displaystyle f(n)$ that gives the number in reverse.
