Statistics at a glance

To understand these in a broader context, see groups of order 3.2^n

The number 192 has prime factorization 192 = 2^6 \cdot 3. There are only two prime factors of this number. Order has only two prime factors implies solvable (by Burnside's p^aq^b-theorem) and hence all groups of this order are solvable groups (specifically, finite solvable groups). Another way of putting this is that the order is a solvability-forcing number. In particular, there is no simple non-abelian group of this order.

Quantity Value Explanation
Total number of groups 1543
Number of abelian groups 11 (number of abelian groups of order 2^6) times (number of abelian groups of order 3^1) = (number of unordered integer partitions of 6) times (number of unordered integer partitions of 1) = 11 \times 1 = 11. See classification of finite abelian groups and structure theorem for finitely generated abelian groups.
Number of nilpotent groups 267 (number of groups of order 64) times (number of groups of order 3) = 267 \times 1 = 267. See number of nilpotent groups equals product of number of groups of order each maximal prime power divisor, which in turn follows from equivalence of definitions of finite nilpotent group.
Number of solvable groups 1543 There are only two prime factors of this number. Order has only two prime factors implies solvable (by Burnside's p^aq^b-theorem) and hence all groups of this order are solvable groups (specifically, finite solvable groups). Another way of putting this is that the order is a solvability-forcing number. In particular, there is no simple non-abelian group of this order.
Number of simple groups 0 Follows from all groups of this order being solvable.

GAP implementation

The order 192 is part of GAP's SmallGroup library. Hence, any group of order 192 can be constructed using the SmallGroup function by specifying its group ID. Also, IdGroup is available, so the group ID of any group of this order can be queried.

Further, the collection of all groups of order 192 can be accessed as a list using GAP's AllSmallGroups function.

Here is GAP's summary information about how it stores groups of this order, accessed using GAP's SmallGroupsInformation function:
