## Abstract

An arithmetic circuit or formula is multilinear if the polynomial computed at each of its wires is multilinear. We give an explicit example for a polynomial f(x _{1}, ..., x _{n}), with coefficients in {0,1}, such that over any field: 1. f can be computed by a polynomial-size multilinear circuit of depth O(log ^{2} n). 2. Any multilinear formula for / is of size n ^{(log n)}. This gives a super-polynomial gap between multilinear circuit and formula size, and separates multilinear NC _{1}. circuits from multilinear NC _{2} circuits.
