Other than the prisms and anti-prisms, there are a number of acrons that have been discovered in recent years.
A full list of possible apolydronic acrons is as follows. In all cases N should be taken as excluding the numbers 3,4,5,6,8 and 10 and being equal to or larger than the second number listed.
