Visual Studio was taking too long to load, so I did it in JavaScript since I could test in my console. This will print out all the choices. (Also it sounds more like a “what’s the algorithm for this?” not “what’s the algorithm for this in C#<\/em>?”)<\/p>\n

function makeGroup(id, count) {\n  var result = [];\n  for (var i = 1; i <= count; i++) {\n    result.push(id + i);\n  }\n  return result;\n}\n\nfunction choose(group, count) {\n  if (count === 1) {\n    var result = [];\n    for (var i = 0; i < group.length; i++) {\n      result.push([group[i]]);\n    }\n    return result;\n  }\n  if (count === 2) {\n    var result = [];\n    for (var i = 0; i < group.length; i++) {\n      for (var j = 0; j < group.length; j++) {\n        if (i !== j && \n            i < j) {\n          result.push([group[i], group[j]]);\n        }\n      }\n    }\n    return result;\n  }\n  if (count === 3) {\n    var result = [];\n    for (var i = 0; i < group.length; i++) {\n      for (var j = 0; j < group.length; j++) {\n        for (var k = 0; k < group.length; k++) {\n          if (i !== j && i !== k && j !== k &&\n              i < j && j < k) {\n            result.push([group[i], group[j], group[k]]);\n          }\n        }\n      }\n    }\n    return result;\n  }\n}\n\nvar groupA = makeGroup('A', 2);\nvar groupB = makeGroup('B', 2);\nvar groupC = makeGroup('C', 3);\nvar groupD = makeGroup('D', 1);\n\nchoose(groupA, 1).forEach(function (a) { \n  choose(groupB, 2).forEach(function (b) {\n    choose(groupC, 3).forEach(function (c) {\n      choose(groupD, 1).forEach(function (d) {\n        console.log(a + \" \" + b[0] + \" \" + b[1] + \" \" + c[0] + \" \" + c[1] + \" \" + c[2] + \" \" + d[0]);\n      });\n    });\n  });\n});\n<\/code><\/pre>\n
Example output:<\/p>\n
A1 B1 B2 C1 C2 C3 D1\nA2 B1 B2 C1 C2 C3 D1\n<\/code><\/pre>\n
\n
To see an example of it working, you can do:<\/p>\n
var testGroup = makeGroup('T', 4);\n\nvar choose1 = choose(testGroup, 1);\nvar choose2 = choose(testGroup, 2);\nvar choose3 = choose(testGroup, 3);\n\nconsole.log(JSON.stringify(choose1));\nconsole.log(JSON.stringify(choose2));\nconsole.log(JSON.stringify(choose3));\n<\/code><\/pre>\n
And see that it chooses correctly:<\/p>\n
[[\"T1\"],[\"T2\"],[\"T3\"],[\"T4\"]]\n[[\"T1\",\"T2\"],[\"T1\",\"T3\"],[\"T1\",\"T4\"],[\"T2\",\"T3\"],[\"T2\",\"T4\"],[\"T3\",\"T4\"]]\n[[\"T1\",\"T2\",\"T3\"],[\"T1\",\"T2\",\"T4\"],[\"T1\",\"T3\",\"T4\"],[\"T2\",\"T3\",\"T4\"]]\n<\/code><\/pre>\n<\/p><\/div>\n
