user: 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?
Columns: ['Group', 'Half-Life (s)', 'Decay Constant (s −1 )', 'Yield, Neutrons per Fission', 'Fraction']
Types: ['real', 'real', 'real', 'real', 'real']
Sample row: [1.0, 55.72, 0.0124, 0.00052, 0.000215]
