Absract. This article
analyses geometric constructions by origami when up to nφ
simultaneous folds may be done at each step. It shows that any arbitrary angle
can be m-sected if the largest prime factor of m is p ≤ n+2. Also, the regular m-gon can be constructed if the largest prime factor of φ(m) is q ≤ n+2, where φ is Euler's totient
function.
