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

### 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?

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

### Response:
SELECT SUM Yield, Neutrons per Fission FROM table WHERE Decay Constant (s −1 ) < 0.301 AND Half-Life (s) = 22.72 AND Group > 2
