- I'm very sorry, this is NOT the correct answer. I found that some
- hours after posting the quoted article (again some CPU seconds on
- one processor) but had no terminal available, so with some delay:
-
- The correct answer should be
-
- 1E+10 000 000 (Base 7).
-
- (That's one of the disadvantages of these bio-cpu with their complex
- OS: They make mistakes. But one of the major advantages is: They might
- find out they made a mistake :-)
