Automorphisms of Lubotzky–Phillips–Sarnak graphs
Sorry, I'm not seeing exactly how quotienting down to a multigraph on one vertex informs the automorphisms of the given LPS graph. I will look into how the LSV graphs connect, thank you.

Is $\mathbb{Z}[i,\varphi]$ a Euclidean domain?
Hello all, in case anyone is still interested in this problem, the result turns out to be true and I have added a writeup as an answer below.

Status of finite-dimensional Ando's theorem
Fantastic, this is very helpful! Do you happen to know if there is anything towards a constructive version of McCarthy–Shalit's theorem?

Polynomial and rational approximation of continuous functions in $\mathbb{C}$
Thank you, this resolves the first and third versions. Towards the second version, as I understand it, Weierstrass' theorem only guarantees existence. Is there a version which allows one to compute the specific approximation, with guarantees relating the uniform precision to the degree, or does that require other machinery?
