Projective general linear group:PGL(2,11)

Definition

This group is defined as the projective general linear group of degree two over field:F11.

Function Value Similar groups Explanation
order (number of elements, equivalently, cardinality or size of underlying set) 1320 groups with same order As PGL(2,q), q = 11: q^3 - q = q(q-1)(q+1) = 11^3 - 11 = (11)(10)(12) = 1320

GAP implementation

Group ID

This finite group has order 1320 and has ID 133 among the groups of order 1320 in GAP's SmallGroup library. For context, there are groups of order 1320. It can thus be defined using GAP's SmallGroup function as:

SmallGroup(1320,133)

For instance, we can use the following assignment in GAP to create the group and name it G:

gap> G := SmallGroup(1320,133);

Conversely, to check whether a given group G is in fact the group we want, we can use GAP's IdGroup function:

IdGroup(G) = [1320,133]

or just do:

IdGroup(G)

to have GAP output the group ID, that we can then compare to what we want.
