Marvellous Maths Challenge Answer:

All three contestants got the same number correct in the same position, meaning two, one or zero letters are in the right place. All combinations with one or two correct lead to contradictions, so all four got every position wrong. From that we deduce that the third in the list isn’t B, D or C so must be A, meaning the second must be C, and the correct order is BCAD. Hence a Sentonium has more legs than a Fettlepod.
