user: Question: What is the decay constant with a half-life less than 22.72, a yield, neutrons per fission of 0.0031000000000000003, and a group number less than 3?
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]
SQL:

assistant: SELECT "Decay Constant (s −1 )" FROM "Table" WHERE "Half-Life (s)" < 22.72 AND "Yield, Neutrons per Fission" = 0.0031000000000000003 AND "Group" < 3.0;
