Statistics at a glance

The number 480 has the prime factorization:

\! 480 = 2^5 \cdot 3^1 \cdot 5^1 =64\cdot 3 \cdot 5

Quantity Value Explanation
Total number of groups up to isomorphism 1213
Number of abelian groups (i.e., finite abelian groups) up to isomorphism 7 (Number of abelian groups of order 2^5) times (Number of abelian groups of order 3^1) times (Number of abelian groups of order 5^1) = (number of unordered integer partitions of 5) times (number of unordered integer partitions of 1) times (number of unordered integer partitions of 1) = 7 \times 1 \times 1 = 7. See classification of finite abelian groups and structure theorem for finitely generated abelian groups.
Number of nilpotent groups (i.e., finite nilpotent groups) up to isomorphism 51 (Number of groups of order 32) times (Number of groups of order 3) times (Number of groups of order 5) = 51 \times 1 \times 1 = 51. 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 1082
Number of solvable groups (i.e., finite solvable groups) up to isomorphism 1187 See note on non-solvable groups
Number of non-solvable groups up to isomorphism 26 All the non-solvable groups have alternating group:A5 as the unique simple non-abelian composition factor and three 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 perfect groups up to isomorphism 0

GAP implementation

The order 840 is part of GAP's SmallGroup library. Hence, any group of order 840 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 840 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.
  IdSmallGroup is available for this size.
