I'm going to ignore the GF(32) part in what follows, so it suffices to say that they're simply numbers from 0 to 31 inclusive, with weird addition and ...

Pieter Wuille's comment gives a nice summary: basically: take a bech32 string, xor a 1 into the last character, then push or pop as many 'q's as you like, and then xor a 1 into the last character again... should always give you a valid new bech32 string Checksum code taken from Bitcoin Core is: uint32_t PolyMod(const data& v) { uint32_t c = 1; ...

It is primarily used for the regression tests, hence the name regtest. Testnet is the public testing network which is very similar to mainnet, the main network.
