 OFFSET 1,1 COMMENTS a(6) has more than 140 decimal digits and is too big to display. - L. Edson Jeffery, Jan 28 2013 LINKS FORMULA a(n) = floor((Pi^Pi)^Pi)^...^Pi) (Pi appears n times). a(n) = floor(Pi^(Pi^(n-1))). - Charles R Greathouse IV, Jan 28 2013 EXAMPLE Pi^Pi = 36.4621596072079, so a(2) = 36.
