In this paper, we study the contribution of the theory of grossone to the study of infinigons in the hyperbolic plane. We can see that the theory of grossone can help us to obtain a much more classification for these objects than in the traditional setting.ACM-class: F.2.2., F.4.1, I.3.5 keywords: tilings, hyperbolic plane, infinigons, grossoneIn [3], an algorithmic approach to the infinigons was given by this author. Infinigons of the hyperbolic plane are polygons with infinitely many sides. It is the case that there are infinitely many such objects and that, among them, there is an infinite family which tiles the hyperbolic plane by applying to an initial infinigon the process which is used to obtain a tessellation from an ordinary regular convex polygon of that plane. The existence of infinigons which tiles the plane appear already in [1] and in [2]. In [3], it was proved that for any angle α with α ∈]0..π[ it is possible to construct an infinigon such that consecutive sides make an angle of α. Moreover, such an infinigon tiles the plane by reflection in its sides and, recursively, of its images in their sides, when α = 2π k with k being a positive integer with k ≥ 3 and only in this case. As already mentioned, [3] gives an algorithmic construction for the tiling defined by an infinigon whose angle is 2π k with k ≥ 3.
