Question: What is the lowest group number that has a Fraction less than 0.000748, a Half-Life of 55.72 and a Decay Constant larger than 0.012400000000000001?
SQL: SELECT MIN("group") FROM prompt_neutron_data WHERE "fraction" < 0.000748 AND "half_life_s" = 55.72 AND "decay_constant_s_1" > 0.012400000000000001

Question: What is the lowest Half-Life with a Yield, Neutrons per Fission greater than 0.0054600000000000004 and a Fraction less than 0.002568?
SQL: SELECT MIN("half_life_s") FROM prompt_neutron_data WHERE "yield_neutrons_per_fission" > 0.0054600000000000004 AND "fraction" < 0.002568
