2026-05-02 05:00:52 +0000 <LdyIQ> also permutations are super basic that's just a permutation group
2026-05-02 04:58:06 +0000 <EvanR> monads for nothing and theorems for free
2026-05-02 04:56:55 +0000 <LdyIQ> that's like the basis for a lot of algebraic geometry
2026-05-02 04:56:45 +0000 <LdyIQ> monochrom, huh? free structures model combinatorics all the time

2026-05-02 04:33:21 +0000 <monochrom> If you have heard of "free" and know what it means, then algebraic data types model free structures in combinatorics, e.g., sequences and trees. However, "clearly", they don't model non-free, quotiented-out structures such as combinations and permutations.
