Someone made a mistake somewhere because a few of the current posts are wrong. I will use #70 as the correction point. It should have been 308061521170129, very close but not exact, then comes 498454011879264. After that the number 806515533049393.

I noticed that too. My reference:

Nichito I do not know where you are getting your numbers from but #76 is also wrong, by one digit. I checked with two sources, a program and website and they both say that 8944394323791464 is the correct number. After that comes 14472334024676221.

The program I use is posted in python code snippets and the website is

hey guys... it seems we lost the numbers' order... here comes #78:
