The oriented swap process is a model for a random sorting network, in which N particles labeled 1,...,N arranged on the discrete lattice [1,N] start out in increasing order and then perform successive adjacent swaps at random times until they reach the reverse configuration N,...,1.

In this talk, based on joint work with Elia Bisi, Fabio Cunden and Shane Gibbons, I will discuss several new exact distributional identities between a random vector encoding the termination time and random vectors in the corner growth process, a well-known model for randomly growing Young diagrams, or equivalently what is known as last passage percolation. The main identity is still conjectural, and would imply a limiting Tracy-Widom GOE law for the termination time.

The talk will include entertaining computer simulations and a demonstration of computer-assisted proofs.
