Little things that matter in language design

Of course it's meaningless. There's no such thing as a set of digits that are "random" or "non-random". You can take a sequence generator and run some statistical tests, but that doesn't prove anything. You can test a sequence of digits for compressibility, but that also doesn't prove anything. The digits in the decimal expansion of pi pass all kinds of statistical tests for randomness, but they are assuredly not "random".
As for a pattern, given a finite sequence of digits, you can construct any pattern you like. I could construct a degree-71 polynomial that fits the 71 digits you posted and say "Yes, that's the generator!"

Well, at the parties I go to, people don't usually open the conversation with "69804177583220909702029165734725158290463091035903784297757265172087724".

That would be a pattern, but not an interesting one.

A non-interesting pattern would be something like the observation "this is a number!" or the observation that all digits from 0 to 9 occur.
