The following quote from the documentation gives idea what the compressor consists of:

Switches

• -bN Set maximum blocksize in kb (def: -b2048, min: -b128, max: -b16383)
• -a Disable automatic blocksize detection
• -e Disable EOL filter
• -f Disable FLT32 filter
• -l Disable DELTA filter
• -z Disable LZP preprocessing stage
• -w Disable BWT stage
• -t Replace BWT with ST 21 bit (faster for big blocks)
• -r Disable RLE after-BWT stage
• -d Disable DCE (Distance+Entropy Coding) stage
• -o Do not omit BWT & RLE stages when outputsize > inputsize

[EOLF] + [FLT32] + [DELTA] + [LZP] + [BWT|ST 21bit] + [RLE-EXP] + [DCE]

• EOLF - End Of Line Filter
• FLT32 - Filter for 32-bit executables,
• DELTA - Delta filter (records prepocessing),
• LZP - Lempel-Ziv preprocessor using hash-table & 4-byte context,
• BWT - Burrows-Weeler Transform,
• ST21bit - 21 bit Shindler Transform,
• RLE-EXP - RLE exponential algorithm,
• DCE - Distance Coding + Entropy coding.

The compressor is featured in the BWT comparison.
