Table schema:
CREATE TABLE table_name_99 (group INTEGER, decay_constant__s_−1__ VARCHAR, fraction VARCHAR, half_life__s_ VARCHAR)

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?
SQL: SELECT MIN(group) FROM table_name_99 WHERE fraction < 0.000748 AND half_life__s_ = 55.72 AND decay_constant__s_−1__ > 0.012400000000000001
