This feature vector is 8000-dimentional feature vector wich is computed from tri-gram probability matrix T obtained from PSSM Matrix.to achieve this purpose elements in three successive rows and arbitrary columns are multiplied together then these results are added together by changing variable i from 1 to L-1, which i is counter of row and L indicates protein length. since there are 20 columns thus final feature vector would be of length 8000.
