In 1963, Thompson, with the late Walter Feit, published a proof of the theorem that «every finite group ofodd order is soluble,» a mathematical way of saying that objects with an oddnumberof symmetries can be broken down into simpler shapes.
2.OA.C.3 Determine whether a group ofobjects (up to 20) has an odd or even numberof members, e.g. by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
