This means that two polyforms are considered the same if one is a rotation of the other. However, reflections of chiral polytopes are considered distinct. %C A371062 The ratio a(n)/A343909(n) -> 2 as n -> infinity. %H A371062 Peter Kagey, <a href="/A371062/a371062_1.png">A photograph of the a(4)=11 polyforms 3D printed</a>. %Y A371062 Cf.
