The 228th mitzvah is that we are commanded to execute by burning1 those who transgress certain mitzvos.

The source of this mitzvah is G‑d's statement2 (exalted be He), "both he and they shall be burned with fire." I will point out the mitzvos which are punishable by sereifa when listing the prohibitions.

The details of this mitzvah are explained in the 7th chapter of tractate Sanhedrin.
