This paper is based on MMCS SFEDU thesis
In this paper I report on formalizing a Moebius strip and on porting a proof of equivalence of fibration and family of types using the proof assistant Arend. The former task is a demonstration of basic Arend features and the latter is an evidence of a correspondence between basic constructions of homotopy and type theories. The code can be found in Arend Groupoid Infinity repository (moebius strip: Moebius.ard, proof: Fiber.ard.
