Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
What is the lowest Half-Life with a Yield, Neutrons per Fission greater than 0.0054600000000000004 and a Fraction less than 0.002568?

### Inputs:
table_name: table, columns: ['Group', 'Half-Life (s)', 'Decay Constant (s −1 )', 'Yield, Neutrons per Fission', 'Fraction']

### Response:
SELECT MIN Half-Life (s) FROM table WHERE Yield, Neutrons per Fission > 0.0054600000000000004 AND Fraction < 0.002568
