Abstract: The Majorana representation of symmetric N-qubit states is employed here toinvestigate how correlation information of the whole pure symmetric state getsimprinted in its parts. It is shown that reduced states of N - 1 qubitsuniquely specify the entire class of pure N qubit states containing twodistinct spinors.
