## Pythia-3-1

### Info

A simple example of an infinite series of substitutions with tilings of statistical circular symmetry. It is shown in [Frettloeh:STWCS not found], that all tilings in this series posses statistical circular symmetry. The substitution factors are `$s2m$`

, where s is the largest root of `$xm-xk-1$`

. Each pair of integers `$(m,k)$`

, where `$m>k, m>2, k>0$`

, encodes a such a Pythia substitution. The case `$m=4, k=2$`

yields the golden pinwheel substitution.
