instruction: What is the yield, neutrons per fission of the group with decay constants less than 0.301, a half-life of 22.72, and a group number larger than 2?
response: SELECT SUM(yield), _neutrons_per_fission FROM table_name_77 WHERE decay_constant__s_−1__ < 0.301 AND half_life__s_ = 22.72 AND group > 2
