Abstract

We investigate the moments of \(3\)-step and \(4\)-step uniform random walk in the plane. In particular, we further analyse a formula conjectured in BNSW expressing \(4\)-step moments in terms of \(3\)-step moments. Diverse related results including hypergeometric and elliptic closed forms for \(W_4(\pm 1)\) are given and two new conjectures are recorded.
