Factorization and useful forms

The number 960 has prime factors 2, 3, and 5, and prime factorization:

\! 960 = 2^6 \cdot 3^1 \cdot 5^1 =64\cdot 3 \cdot 5

Other useful expressions for this number are:

\! 960 = 2(5^2 - 1)(5^2 - 5) = 2^3 \cdot 5!

Group counts

Quantity Value Explanation
Total number of groups up to isomorphism 11394
Total number of abelian groups (i.e., finite abelian groups) up to isomorphism 11 (Number of abelian groups of order 2^6) times (Number of abelian groups of order 3^1) times (Number of abelian groups of order 5^1) = (number of unordered integer partitions of 6) times (number of unordered integer partitions of 1) times (number of unordered integer partitions of 1) = 11 \times 1 \times 1 = 11. See classification of finite abelian groups and structure theorem for finitely generated abelian groups.
Total number of nilpotent groups (i.e., finite nilpotent groups) up to isomorphism 267 (Number of groups of order 64) times (Number of groups of order 3) times (Number of groups of order 5) = 267 \times 1 \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 supersolvable groups (i.e., finite supersolvable groups) up to isomorphism 10723
Total number of solvable groups (i.e., finite solvable groups) up to isomorphism 11287 See note on non-solvable groups
Number of non-solvable groups up to isomorphism 107 All the non-solvable groups have alternating group:A5 as the unique simple non-abelian composition factor and four cyclic group:Z2s as the other composition factors
Number of simple groups up to isomorphism 0
Number of quasisimple groups up to isomorphism 0
Number of almost simple groups up to isomorphism 0
Number of almost quasisimple groups up to isomorphism 0
Number of semisimple groups up to isomorphism 0
Number of perfect groups up to isomorphism 2 One of the groups is inner automorphism group of wreath product of Z2 and A5. This is the smallest order for which there are examples to show that perfect not implies semisimple.

GAP implementation

The order 960 is part of GAP's SmallGroup library. Hence, any group of order 960 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 960 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:

  For the selection functions the values of the following attributes
  are precomputed and stored:
     IsAbelian, IsNilpotentGroup, IsSupersolvableGroup, IsSolvableGroup,
     LGLength, FrattinifactorSize and FrattinifactorId.

  This size belongs to layer 2 of the SmallGroups library.
