Question: 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?
SQL: SELECT SUM("Yield, Neutrons per Fission") FROM "2-1221448-1" WHERE "Decay Constant (s −1 )" < 0.301 AND "Half-Life (s)" = 22.72 AND "Group" > 2.0;

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?
SQL: SELECT COUNT("Decay Constant (s −1 )") FROM "2-1221448-1" WHERE "Half-Life (s)" < 22.72 AND "Yield, Neutrons per Fission" = 0.0031000000000000003 AND "Group" < 3.0;

Question: What is the lowest half-life with a yield, neutrons per fission bigger than 0.0031000000000000003 and a decay constant less than 0.030500000000000003?
SQL: SELECT MIN("Half-Life (s)") FROM "2-1221448-1" WHERE "Yield, Neutrons per Fission" > 0.0031000000000000003 AND "Decay Constant (s −1 )" < 0.030500000000000003;
