This class of groups was introduced by Fine and Rosenberger and independently by Vinberg. Some conditions for the generalized tetrahedron groups to have a rational Euler characteristic are shown here and the values of the Euler characteristics in these cases are calculated. In addition here are some geometrical applications of the Euler characteristic of generalized tetrahedron groups.1 2 Birkhäuser Verlag, Basel, 1996 generalized tetrahedron group nationallicence Euler characteristic nationallicence Results in Mathematics Birkhäuser-Verlag 29/3-4(1996-05-01), 371-375 0378-6218 29:3-4<371 1996 29 25 https://doi.org/10.1007/BF03322232 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/BF03322232 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Stille Michael Fachbereich Mathematik, Universität Dortmund, 44221, Dortmund, Germany aut NATIONALLICENCE 773 0- Results in Mathematics Birkhäuser-Verlag 29/3-4(1996-05-01), 371-375 0378-6218 29:3-4<371 1996 29 25 Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
