36 The theoretical maximum number of distance bits specified for large window brotli, for 64-bit encoders and decoders\&. Even when in practice 32-bit encoders and decoders only support up to 30 max distance bits, the value is set to 62 because it affects the large window brotli file format\&. Specifically, it affects the encoding of simple huffman tree for distances, see Specification RFC 7932 chapter 3\&.4\&.
