A sample iterated small cancellation theory for groups of Burnside type

We develop yet another technique to present the free Burnside group $B(m,n)$ of odd exponent n with m≥2 generators as a group satisfying a certain iterated small cancellation condition. Using the approach, we provide a reasonably accessible proof that $B(m,n)$ is infinite with a moderate bound $n > 2000$ on the odd exponent n.
