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

### Instruction:
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?

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

### Response:
SELECT COUNT Decay Constant (s −1 ) FROM table WHERE Half-Life (s) < 22.72 AND Yield, Neutrons per Fission = 0.0031000000000000003 AND Group < 3
