Using a computer we classify licci level* squarefree monomial ideals I with codimension 3 and with dim S/ I≤ 4. We also show the following two conditions are equivalent: (1) ISm is licci, (2) the twisted conormal module of I is Cohen-Macaulay, where S is a polynomial ring and m is its graded maximal ideal.
