I think you might have miscalculated bits per bytes here?

8 * 17,763/64,860 = 2.19

Also, I attempted to implement this as described in this paper (variable length encoding the letters and the offsets, utilized L, and dropped F entirely because all words are the same length, N didn't make a big difference).

I achieved a naive size of 20,560 bytes, which I didn't have confidence implementing more advanced techniques outlined in the paper would get the size down sufficiently to compete with using a trie+Huffman representation (15,599 bytes, https://github.com/adamcw/wordle-trie-packing#all-words).

8 * 15,599/64,860 = 1.92 bits per byte.
