I looked it up on Wikipedia.

In mathematics, the Dedekind numbers are a rapidly growing sequence of integers named after Richard Dedekind, who defined them in 1897. The Dedekind number M(n) is the number of monotone boolean functions of n variables. Equivalently, it is the number of antichains of subsets of an n-element set, the number of elements in a free distributive lattice with n generators, and one more than the number of abstract simplicial complexes on a set with n elements.

Pretty simple to understand. I mean, I understand it, for sure. Totally.

Ah, yes, those things, of course.

Glad we cleared that up. In hindsight, it was pretty obvious from the start.

Ah, yes. I know ~~some~~ none of these words.

I understood most of the words, just the ones that I didn't made the rest incomprehensible garbledygoop

Good work everyone. I stay more with the stereo boolean variables, but the news about those lattices being free now is really great stuff. We really did something here

rapidly growing

1 found in 32 years

Lol, I thought that at first, but I'm pretty sure it's in how much larger the next number is to the last one.

[–] [email protected] 2 points 11 months ago

Yes that's what it means, what is rapidly growing is the value of the next number in the sequence, not the amount of numbers we discovered!
