-
- GNU Calc on a Sparc 1 does it in 3.25 real seconds... and then
- takes 2 minutes 58 seconds to print the answer.
-
- It does 7 ^ (7 ^ 7) in 12 minutes 24 seconds, yielding...
- 375 ...(695969 digits deleted)... 343
-
- To print the answer to that one takes 17 hours 2 minutes!
- I guess that part of their package could use some work. :-/
