I am responding to you message about pi.
I memorized pi as well, however, only to 50 digits; Although, you can be assured that I will memorize more than 54 digits now that I know someone else knows more.
Also from memory, (Mine that is):
3.14159265358979323846264338327950288419716939937510 and "5820", and finally 9 !!!!!
That would be one more than you posted if my calculations are correct.
Let the battle of memorization begin!
