CREATE TABLE table_203_266 (id DECIMAL, "group" TEXT, "members" DECIMAL, "caucusing" DECIMAL, "total" DECIMAL)

what group has the same number of caucusing members as rpr group ?
SELECT "group" FROM table_203_266 WHERE "group" <> 'rpr group' AND "caucusing" = (SELECT "caucusing" FROM table_203_266 WHERE "group" = 'rpr group')
SELECT "group" FROM "table_203_266" WHERE "caucusing" = (SELECT "caucusing" FROM "table_203_266" WHERE "group" = 'rpr group') AND "group" <> 'rpr group'
