sipa: In BIP-0173 you folks write "Even though the chosen code performs reasonably well up to 1023 characters, other designs are preferable for lengths above 89 characters (excluding the separator)."

An you elaborate on this? Why are other designs better, and how did you arrive at the 89 character value?

roconnor: algebraically, the bech32 checksum is a BCH code with d=4 with length 1023, but among all such codes (and several other classes of BCH codes for q=32), one was selected that exhibits distance 5 up to length 89 (computationally determined)
<sipa>
so if you cared about behavior at longer lengths, you may want a different selection
<roconnor>
ah, the code distance is 4, so it only guarentees to detect 3 errors beyond 89.
<sipa>
exactly
<sipa>
it also means if you care about things like error correction/detection, and you want to use algebraic techniques rather than brute force, you're limited to what distance 4 allows
<sipa>
the reference code for the error detection uses a hybrid algebraic + exhaustive technique to exploit distance 5
<roconnor>
Dang.
<roconnor>
you mean the reference code for error correction?
<sipa>
well it only reports the positions in which it would make corrections, not the actual errors
<sipa>
but yes, it's an error correction algorithm

ah
<roconnor>
you mean the reference code for error location.
<sipa>
right
