Consider a polygon $P$, where $t(P)$ signifies the total number of methods in which $P$ can be tiled utilizing rhombi and squares, each with an edge length of 1. It's important to note that distinct rotations and reflections are considered as separate tilings.
Take for instance, if $O$ is a regular octagon with an edg... | codefeedback | [
