User blog comment:Chronolegends/Tetration related to iterated exponentiation/@comment-10262436-20160509134300

Hi.

I just calculated the same thing on my blog called:  "Beta Function Code Version 3".

I agree it is noteworthy to add to the main page, if only, to clearly show how to calculate tetration sums correctly and avoid some of the easy errors you can make.

cheers
