(This FUN fact was derived from the current OEIS stripped database.)

How excitingly uninteresting!

Thrillingly boring!

Background

I came across a blog post claiming that 11630 was the First Uninteresting Number in June 2009. There are even some updates about how it it increased to 12407 in November 2009 and later to 14228 in November 2013. So naturally I wondered what the current lowest uninteresting number is.

Note that this is not a paradox, as the blog post confirms:

> Update [June 13, 2009]: I got word back via e-mail today that this sequence didn't make the cut. So there you have it — these numbers truly are uninteresting.

;-)
